Polarization-independent and all-optically modulated multiband metamaterial coherent perfect absorber

A polarization-independent, all-optically modulated multiband metamaterial coherent perfect absorber (CPA) is proposed. Numerical simulation results reveal that the absorber can be controlled over a wide range of amplitudes by changing the phase difference of two incident light beams. The all-optical modulation can be extended to telecom wavelengths, allowing for simultaneous modulation of absorption at 1310 nm and 1550 nm. In addition, switchable logical gate states can be achieved at the dip between absorption peaks. The proposed absorber utilizes bound states in the continuum (BIC) mode to realize another absorption band, expanding the application range and enhancing its flexibility. The results suggest that the proposed absorber has a promising modulated optical response, with potential applications in developing optical switches, smart multi-band absorbers, telecom devices and so on.

Thermally tunable ethanol impregnated PDMS/CoZTO/SWCNT composite architecture for smart electromagnetic shielding

Shape memory elastomer composites with externally stimulated shielding capability are greatly sought to protect high-end artificial intelligence-based electrical and telecommunication devices in the military, aerospace, robotics, etc., from electromagnetic interference (EMI). However, the fabrication of such composites integrated with externally responsive green EMI shielding capabilities is promising but greatly challenging. Herein, ethanol (thermally active phase) mixed polydimethylsiloxane (PDMS)/single wall carbon nanotube (SWCNT)/cobalt doped zinc tin oxide (CoZTO) hybrid composite with an active guest method was devised. This design strategy explores how the thermally controlled liquid-gas phase transition led microstructural modifications regulate the macroscopic shielding features like absorption enhancement and reflection minimization. The composite adapts the 72.18 % volumetric actuation by liquid-to-vapor phase transition of ethanol at 80 °C, promoting the total EMI shielding value up to 48.77 dB from 18.4 dB at 20 GHz due to microstructure induced electromagnetic modifications. Additionally, a green index of 7.2 confirms the absorption dominance over reflection shielding in the studied composite. Furthermore, ethanol-generated foamed architecture of composite offers pressure-sensitive on-off shielding tunability, which accounts for the potential use in manufacturing advanced RF switches.

Analysis and Implementation of Controlled Semiconductor Switch for Ultra-Wideband Radar Sensor Applications.

All ultra-wideband (UWB) sensor applications require hardware designed directly for their specific application. The switching of broadband radio frequency and microwave signals is an integral part of almost every piece of high-frequency equipment, whether in commercial operation or laboratory conditions. The trend of integrating various circuit structures and systems on a chip (SoC) or in a single package (SiP) is also related to the need to design these integrated switches for various measuring devices and instruments in laboratories, paradoxically for their further development. Another possible use is switching high-frequency signals in telecommunications devices, whether mobile or fixed networks, for example, for switching signals from several antennas. Based on these requirements, a high-frequency semiconductor integrated switch with NMOS transistors was designed. With these transistors, it is possible to achieve higher integration than with bipolar ones. Even though MOSFET transistors have worse frequency characteristics, we can compensate them to some extent with the precise design of the circuit and layout of the chip. This article describes the analysis and design of a high-frequency semiconductor integrated switch for UWB applications consisting of three series-parallel switches controlled by CMOS logic signals. They are primarily intended for UWB sensor systems, e.g., when switching and configuring the antenna MIMO system or when switching calibration tools. The design of the switch was implemented in low-cost 0.35 µm SiGe BiCMOS technology with an emphasis on the smallest possible attenuation and the largest possible bandwidth and isolation. The reason for choosing this technology was also that other circuit structures of UWB systems were realized in this technology. Through the simulations, individual parameters of the circuit were simulated, the layout of the chip was also created, and the parameters of the circuit were simulated with the parasitic extraction and the inclusion of parasitic elements (post-layout simulations). Subsequently, the chip was manufactured and its parameters were measured and evaluated. Based on these measurements, the designed and fabricated UWB switch was found to have the following parameters: a supply current of 2 mA at 3.3 V, a bandwidth of 6 GHz, an insertion loss (at 1 GHz) of -2.2 dB, and isolation (at 1 GHz) of -33 dB, which satisfy the requirements for our UWB sensor applications.

The Role of Artificial Intelligence (AI) in the Academic Paper Writing and Its Prospective Application as a Co-Author: A Letter to the Editor

Dear Editors, I have read your editorials with great interest [1,2]. I am interested in sharing my insights concerning the role of artificial intelligence in composing scholarly articles, along with its potential as a collaborative co-author. I extend my heartfelt gratitude for establishing this profoundly valuable platform for discussion. I am aware of the imperative to renew myself academically daily. Perhaps the most exquisite yet arduous facet of academic life resides herein. Sustaining the currency of my domain knowledge, tracking technological advancements, and aligning with the latest research trends often pose formidable challenges. However, these challenges also furnish avenues for continuous self-improvement and exploring topics demanding more profound comprehension. In addition to the facilitation of information access afforded by computers and the internet, artificial intelligence has been incorporated in recent years—my inaugural encounter with artificial intelligence manifested through applications utilized on telecommunication devices. Artificial intelligence finds application across various domains and displays a swiftly burgeoning spectrum of applications. In recent years, significant advancements have transpired in artificial intelligence, culminating in the emergence of numerous Large Language Models (LLMs). Introducing sophisticated and diverse language models has precipitated a remarkable leap in this domain. One such model is the artificial intelligence conversational robot named ChatGPT, equipped with the GPT-3.5.5 language model, which OpenAI unveiled on November 30, 2022. Impressively, this model garnered one million users within five days. Within the academic literature, ChatGPT, a Chat Generative-Being Transformer, is widely acknowledged as a substantial and versatile information resource [3]. So, can ChatGPT be used safely for manuscript writing? As academics, we know that writing an article and adding new knowledge to the literature requires serious dedication. In this context, using ChatGPT for article writing involves significant risks [4]. The biggest problem is accuracy [5]. Artificial intelligence draws its data from the internet environment, where the veracity and reliability of information are persistently subject to debate. The accuracy and reliability of data on the Internet is always controversial. ChatGPT can produce factually inaccurate and inaccurate texts, create biased texts, and in particular, this can undermine the credibility and authority of researchers. Another most critical problem is that it includes ethical concerns. However, we cannot overlook the fact that with the advancement of technology, artificial intelligence has been progressing toward the core of our lives. As a solution, I think that artificial intelligence should be employed with caution, considering its ethical problems, the potential for misapplications, and plagiarism-related concerns. Notably, it can contribute to refining written text rather than printing the entire article. In addition, as you stated, the role, contributions, and process of ChatGPT in the article should be clearly stated. In the literature, it has been said that ChatGPT contributed to various stages, such as data analysis, model development, and interpretation of results [6]. Susnjak [7] has argued that ChatGPT exhibits critical thinking skills and can generate highly realistic texts with minimal input, positing that this poses a threat in online examinations, particularly within higher education settings. Zhai [8] in the context of crafting articles encompassing education and artificial intelligence themes, has emphasized the assertion that ChatGPT could assist researchers in generating coherent, partially accurate, informative, and systematic articles. Alshater [9] has noted that ChatGPT has the potential to improve academic performance, underlined various limitations, such as ethical considerations, and emphasized the importance of combining human analysis and interpretation. So, is it appropriate for ChatGPT to be credited as a co-author? This topic will always be controversial This matter will inevitably remain subject to ongoing debate. The scope of ChatGPT's contribution and the ethical considerations surrounding this practice, coupled with the continued discussions within the academic community, suggest that employing ChatGPT as a co-author carries substantial risks [10]. In a collaborative study where Perlman and ChatGPT served as co-authors [11], Perlman evaluated the text generated by ChatGPT and underscored the possibility of envisioning a new future by considering the ethical concerns, faulty applications, and plagiarism issues associated with artificial intelligence. Similarly, in a comparable endeavor, Srivastava [12] was tasked with using ChatGPT to compose a conference paper and consequently emphasized that, under researcher supervision, ChatGPT could be an efficient application. In conclusion, the assertion that artificial intelligence plays an increasingly significant role in research and scientific discovery is continuously gaining support. However, considering the meticulousness and accuracy required for establishing academic literature across all fields, ChatGPT's practice of generating academic articles from scratch and serving as an assistant author is not aligned with academic norms. There is a need for the development of more nuanced programs in this regard. Especially in the coming days, ChatGPT should prove the information it gives and present the right references for every sentence. Simultaneously, ChatGPT should be revamped in a format that can address ethical concerns. Yours sincerely,

Growth in the use of telehealth creates new challenges and opportunities for implementation in clinical practice. The American Academy of Physical Medicine and Rehabilitation (AAPM&R) assembled an expert group to develop a white paper to examine telehealth innovation in Physical Medicine and Rehabilitation (PM&R). The resultant white paper summarizes how telehealth is best used in the field of PM&R while highlighting current knowledge deficits and technological limitations. The report identifies new and transformative opportunities for PM&R to advance translational research related to telehealth and enhance patient care.

One-way propagation of topologically non-conventional bulk transverse elastic waves in infinite and finite superlattices: Application to low-loss acoustic wave devices

Static superlattices that do not break time-reversal symmetry can support robust topologically protected elastic waves with non-zero amplitude in the forward propagating direction but zero amplitude in the opposite direction. We form a prototypical acoustic wave device by sandwiching a finite superlattice that supports one-way propagating waves between input and detector layers. Compared to conventional elastic waves, topologically protected waves provide a significant benefit for reducing the return loss of the prototypical device. Superlattices supporting topologically protected acoustic waves provide attractive and disruptive solutions for designing the next-generation of low-loss acoustic wave devices for telecommunication or sensing.

Implementation of Decision-Making Algorithms and Key Requirement Approach for Vendor Selection in Telecommunication Device Bidding

The influence of perceived quality is a classic problem in a vendor selection process. To overcome this problem, many algorithms have been used in decision making. In this paper we have carried out the identification of planning team needs and the optimization of the bidding scheme using key requirements to minimize the influence of quality perceptions. The Kano Model Analysis method, the Analytical Hierarchy Process and Technique for Order Preference by Similarity to the Ideal Solution are used to analyze and determine the key requirements in the bidding process for telecommunications equipment needed by the planning team. Vendor selection based on key of requirements specifications is carried out in six stages, namely the preparation stage, requirements search, selection of Key of Requirements specifications, vendor selection, accuracy testing and conclusions. The results of the analysis show that the need for new planning and architecture of telecommunication service providers can increase to NFVi and services. An important criterion for NVFi (Hardware) development is Virtual Infrastructure Management (VIM) with a weight of 22%, while the service criteria are Fixed Services with a weight of 50.94%. Based on the analysis results, the preference value of each telecommunication equipment vendor (supplier) is also obtained.

Towards a sustainable and green approach of electrical and electronic waste management in Rwanda: a critical review.

Electric and electronic equipment (EEE) consumption has grown to worrisome proportions in developing countries (DCS), resulting in massive amounts of electrical and electronic waste (e-waste) being produced. A diagnosis of e-waste proliferation is required for its sustainable management plan in Rwanda. This review is based on open-access papers with e-waste as a keyword, the present situation of EEE, and e-waste in Rwanda. The need for various information communication and technology (ICT) tools, such as end-user devices, cooling-system devices, network equipment, and telecommunication devices, is strongly encouraged by Rwandan national plans, which deem ICT as a vital enabler of knowledge-based economy and development. In 2014, EEE was 33,449 tonnes (t), which is expected to be 267,741 t in 2050, with a yearly increase rate of 5.95%. In this regard, out-of-date EEE is being dumped as e-waste in large quantities and at an increasing rate across Rwanda. E-waste is often disposed of in uncontrolled landfills together with other types of household waste. To address this rising threat, as well as to preserve the environment and human health, proper e-waste management involving e-waste sorting/separation from other waste streams, repairs, reuse, recycling, remanufacturing, and disposal has been proposed.

Fraud Crime through Electronic System Based on Indonesian Positive Law (Decision Study No: 1356/PID/B/2016/PN.BDG)

Today's criminal acts of fraud continue to develop following the development of existing technology, existing legal regulations function to overcome this, but existing regulations cannot reduce these crimes but increase them. This study aims to find out how existing law enforcement is against criminal acts of fraud through electronic systems, knowing various kinds of inhibiting factors in enforcing criminal law against a crime of fraud. This research was carried out using normative juridical methods through library research by examining secondary data including regulations legislation, research results, scientific journals and references. The results of the study provide an illustration, where criminal acts of fraud through electronic systems are in principle the same as fraud in conventional ways, but the difference lies in the evidence or means of action, namely using electronic systems (computers, internet, telecommunication devices), because that is law enforcement. Fraud crimes can still be overcome by Article 378 of the Criminal Code concerning fraud and Article 28 Paragraph (1) of the ITE Law concerning Information and Electronic Transactions Furthermore, obstacles in law enforcement against criminal acts of fraud based on electronic transactions are still influenced by five factors, namely legal factors, law enforcement factors , factors of facilities or facilities that support law enforcement, social factors and cultural factors.

RF Health Safety Limits and Recommendations [Health Matters

The rapid proliferation of cellular mobile telecommunication devices and systems is raising public health concerns about the biological effects and safety of RF radiation exposure. There is also concern about the efficacy of promulgated health safety limits, rules, and recommendations for the RF radiation used by these devices and systems. This article reviews and discusses the U.S. Federal Communications Commission (FCC) notices and rules, International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines, and International Committee on Electromagnetic Safety (ICES) standard for safety levels with respect to human exposure to electric, magnetic, and electromagnetic fields (EMFs). The recently revised RF exposure limits are adjusted only for heating with RF radiation. These limits are largely intended to restrict short-term heating by RF radiation that raises tissue temperatures. They are narrow in scope and are not applicable to long-term exposure at low levels. This review discusses the assumptions underlying the standards and the outdated exposure metrics employed, and concludes that the revised guidelines do not adequately protect children, workers, or the public from exposure to RF radiation or people with sensitivity to electromagnetic radiation from wireless devices and systems. Furthermore, the review discusses important animal data that the standards do not appear to take into account. Moreover, for millimeter-wave radiation from 5G mobile communications, there are no adequate human health effects studies in the published literature. The conclusions by scientific organizations, such as the International Agency for Research on Cancer (IARC), that diverge from these standards are also discussed. The review concludes that many of the recommended limits are debatable and require more scientific justification from the standpoint of safety and public health protection.

Graphene and Fe2O3 filled composites for mitigation of electromagnetic pollution and protection of electronic appliances

With extensive advancement and abundant availability of telecommunication and electronic devices, electromagnetic pollution has become a serious concern not only for human health but also for much sensitive electronic equipment which may fail or malfunction due to electromagnetic interference. Therefore, effective and lightweight electromagnetic interference (EMI) shielding structures are of vital importance for human protection as well as for safeguarding sensitive electronic equipment from interference. In this regard, carbon fiber reinforced composite structures (CFRCS) have proven as one of the best options due to their light weight, extraordinary mechanical properties, and excellent durability. This study explored the synergistic incorporation of graphene and ferric oxide nanoparticles in the CFRCS at various loading concentrations to enhance their electromagnetic shielding effectiveness (EMI SE). According to the results, maximum EMI shielding effectiveness of 95.57 dB was attained at a 4% loading concentration of graphene and a 6% loading concentration of ferric oxide, over a broader frequency range of 0.1 GHz–13.6 GHz. In light of these results, different EMI shielding structures can be developed, including EMI shielding rooms for better protection of humans as well as any sensitive electronic equipment from the harmful effect of electromagnetic radiation. The obtained results are outstanding and may be employed commercially for the protection of electronic equipment and human individuals.

Dynamics of time-modulated, nonlinear phononic lattices.

The propagation of acoustic and elastic waves in time-varying, spatially homogeneous media can exhibit different phenomena when compared to traditional spatially varying, temporally homogeneous media. In the present work, the response of a one-dimensional phononic lattice with time-periodic elastic properties is studied with experimental, numerical and theoretical approaches in both linear and nonlinear regimes. The system consists of repelling magnetic masses with grounding stiffness controlled by electrical coils driven with electrical signals that vary periodically in time. For small-amplitude excitation, in agreement with linear theoretical predictions, wave-number band gaps emerge. The underlying instabilities associated to the wave-number band gaps are investigated with Floquet theory and the resulting parametric amplification is observed in both theory and experiments. In contrast to genuinely linear systems, large-amplitude responses are stabilized via the nonlinear nature of the magnetic interactions of the system, and results in a family of nonlinear time-periodic states. The bifurcation structure of the periodic states is studied. It is found the linear theory correctly predicts parameter values from which the time-periodic states bifurcate from the zero state. In the presence of an external drive, the parametric amplification induced by the wave-number band gap can lead to bounded and stable responses that are temporally quasiperiodic. Controlling the propagation of acoustic and elastic waves by balancing nonlinearity and external modulation offers a new dimension in the realization of advanced signal processing and telecommunication devices. For example, it could enable time-varying, cross-frequency operation, mode- and frequency-conversion, and signal-to-noise ratio enhancements.

CHILDREN ARE MORE EXPOSED TO ELECTROMAGNETIC RADIATION IN COVID-19 LOCKDOWN: A LITERATURE REVIEW

Introduction: The COVID-19 pandemic has significantly affected people's quality of life. Unfortunately, the epidemic continues in various variants and it remains unclear how long it will continue. Children staying at home in the COVID-19 quarantine spent hours in front of the screen with online education. In addition, since they could not go out, they spent their free time in front of the screen using social media, playing computer games or watching movies. The aim of this study is to investigate the effects of low-level electromagnetic radiation (EMR) that children are exposed to at home during the COVID-19 quarantine. Method: The research method is literature review. Results: Studies have shown that, during the quarantine period, children's use of telecommunication devices such as televisions, tablets, smartphones and computers greatly increases. It was determined that the range of radio frequency (RF), Wi-Fi, power lines, visible light and Bluetooth increased in the home environment. The electric and magnetic fields emitted from these devices contain EMR and can seriously harm the health of children, who are structurally more sensitive than adults. Conclusion: There are growing concerns that children staying at home during the COVID-19 pandemic will face health hazards in the future as they are more exposed to EMR.

A Prescription for Internet: Feasibility of a Tablet Loaner Program to Address Digital Health Inequities.

The coronavirus disease 2019 pandemic accelerated the adoption of telehealth technologies. Persistent disparities in telecommunication devices, internet connectivity, and digital literacy, however, undermine the potential for telemedicine to reduce barriers to health care access. Health systems may have a role in addressing these structural inequities. We describe the operationalization and feasibility of an internet-enabled tablet loaner program at a freestanding children's hospital. Between October 2020 and October 2021, pediatricians enrolled families through ambulatory clinics at an academic urban freestanding children's hospital. Eligibility criteria included difficulty accessing virtual care due to lack of stable internet or device. Tablets featured an unlimited data package, access to the patient portal, and virtual visit platform. A private technology company managed device configuration and distribution. To characterize program impact, we compared the proportion of completed clinical encounters during the intervention compared with a preintervention period (March 2020-October 2020) and conducted a qualitative survey with program participants. Participant and visit characteristics were obtained from the electronic medical record and summarized with descriptive statistics. A total of 111 families participated in the tablet loaner program, the majority of whom were Hispanic (51.4%) and black, non-Hispanic (26.1%), and publicly insured (64.9%). Between the preintervention and intervention periods, there was a significant increase in completed video- and phone-based virtual visits (75.3 vs. 79.1%, p = 0.038). The proportion of video-based only visits increased from 82.9 to 88.9%. p < 0.001. Families reported that the tablet improved the patient's ability to receive medical care (93.7%) and was easy to use (93.9%). The tablet loaner initiative was associated with an improvement in markers of virtual visit engagement and health care experience. Efforts to expand telemedicine equity must consider technological access and digital literacy as well as broad coalitions across industry, government, and community organizations.

Compact UWB MIMO Antenna for 5G Millimeter-Wave Applications.

This paper presents a printed multiple-input multiple-output (MIMO) antenna with the advantages of compact size, good MIMO diversity performance and simple geometry for fifth-generation (5G) millimeter-wave (mm-Wave) applications. The antenna offers a novel Ultra-Wide Band (UWB) operation from 25 to 50 GHz, using a Defective Ground Structure (DGS) technology. Firstly, its compact size makes it suitable for integrating different telecommunication devices for various applications, with a prototype fabricated having a total size of 33 mm × 33 mm × 0.233 mm. Second, the mutual coupling between the individual elements severely impacts the diversity properties of the MIMO antenna system. An effective technique of orthogonally positioning the antenna elements to each other increased their isolation; thus, the MIMO system provides the best diversity performance. The performance of the proposed MIMO antenna was investigated in terms of S-parameters and MIMO diversity parameters to ensure its suitability for future 5G mm-Wave applications. Finally, the proposed work was verified by measurements and exhibited a good match between simulated and measured results. It achieves UWB, high isolation, low mutual coupling, and good MIMO diversity performance, making it a good candidate and seamlessly housed in 5G mm-Wave applications.

Tuning structural, electrical, dielectric and magnetic properties of Mg–Cu–Co ferrites via dysprosium (Dy3+) doping

In current research work, Dy3+ substituted Mg0.5Cu0.25Co0.25Fe2‒xDyxO4 (0.0 ≤ x ≤ 0.04 with the step interval of 0.01) soft ferrites were synthesized by the sol–gel auto combustion method. The prepared samples were characterized by the techniques using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), Fourier transform infrared (FTIR) spectroscopy, current–voltage (I–V) measurement, LCR meter, vibrating sample magnetometer (VSM) and Raman. XRD data reveal that the average crystallite size is 49.71 nm and the lattice constant is 0.83703 nm for sample x = 0.03. The non-uniform grain growth was demonstrated by micrographs and impurity-free elemental composition was observed from EDX analysis. The DC resistivity has an increasing and decreasing trend in ferromagnetic and paramagnetic regions with an increase in temperature. Moreover, the high resistivity is observed with the order of 1010 Ω·cm, and the activation energy is 0.944 eV for samples x = 0.03. The dielectric parameters including dielectric constant, dielectric losses, and impedance gradually decrease with the increase in frequency from 8 Hz to 8 MHz. The minimum dielectric loss at high frequency is found for sample x = 0.03. The coercivity (Hc) and saturation magnetization (Ms) are found in the ranges of 520.82–544.02 Oe and 20.5841–21.1473 emu/g, respectively. These observations confirm that dysprosium (x = 0.03) doped MCC-soft ferrites may be applicable in transformer cores, microwave absorbance, and telecommunication devices.

Development of the management system of technical indications of high-power charger-discharger rectifier device

Uninterruptible power supply devices are the main sources of operational DC power supply to control devices and control devices. In addition, the charge-discharge rectifier devices in thermal power plants and substations are autonomous operational current sources of power plants and substations. This source is the main constant and alternating current source for relay protection devices, telecommunication devices, control and monitoring devices in power stations and substations. As switching devices, the most commonly used ones today are thyristor, controlled by the thyristor control electrode. It is possible to control the charging and discharging processes of the batteries. In this case, random charging or discharging of the battery will reduce its service life. Therefore, this article examines its management system. Today’s high-power uninterruptible power supply rectifier devices show that stations and substations are not ready for emergency situations due to their unstable operation and inability to control the state of the battery. Therefore, the improvement of this device remains the major issue.
