A Review on Strategies to Enhance the On-Body Read Range of Passive UHF RFID Tag

Passive Ultra-High-Frequency Radio Frequency Identification (UHF RFID) tag has been implemented as a wearable device for numerous healthcare applications. However, the tag possesses limitations owing to the absorption of electromagnetic radiation by the human body, which significantly reduces the read range of the tag. Thus, the potential strategies to mitigate the effect of the human body need to be addressed. Recently, significant efforts have been made to overcome this shortcoming by incorporating metamaterials or introducing slots to the tag antenna structure. Therefore, this article provides insight into strategies that specifically employ slots, Artificial Magnetic Conductor (AMC), and Split Ring Resonator (SRR). Prior to this, the factors affecting the read range and previously reported studies are briefly discussed. Finally, the future directions for further improvement of these strategies are discussed.

Effect of Relaxation Times on Magnetization of Blood Proton Spins at Steady State using Improved Bloch NMR Fluid Flow Equation

Nuclear magnetic resonance (NMR) is a phenomenon that involves the absorption and re-emission of electromagnetic radiation by blood proton spins flowing through human vessels. NMR is governed by Bloch NMR fluid flow equation, which can be used to define the magnetization of blood proton spins. In the existing literature, the Bloch NMR fluid flow equation has been derived, and it has been observed that the equation does not incorporate certain NMR and blood flow parameters. In this paper, we derived a novel Bloch NMR magnetization flow equation that encompasses NMR parameters such as Larmor frequency of spinning protons and static magnetic field. We utilized the principle of dimensional homogeneity to check the validity of our newly derived NMR flow equation. Furthermore, we investigated the effect of transverse relaxation times of arterial, venous and capillary blood on magnetization of blood spinning protons. We employed Laplace transform method to obtain the steady state solution of the improved Bloch NMR fluid flow equation. MATLAB and Origin software tools were used for data analysis and simulations. Results showed that for varied transverse relaxation times of arterial, venous and capillary blood, respectively, the magnetization distribution of blood spinning protons consists of two components: the linear and the non-linear components. The findings of the study also indicated that capillary blood proton spins exhibit phase coherence. The simulated results may be used by spectroscopists to improve the accuracy of NMR/magnetic resonance imaging (MRI) experiments.

Reversible bonding relates to circular economy enhancement practices, like repair, refurbishment, replacement, or renovation. The physical-chemical, mechanical, and dielectric characteristics were considered to determine the impact of particle size and metal type. Through the investigation of electromagnetic radiation absorption in the composites, it was discovered that the optimal bonding technique could potentially involve a frequency of 915 MHz and a power level of 850 × 103 W/kg, resulting in an efficient process lasting 0.5 min. It was ultimately proven that the newly created hot-melt adhesive formulas can be entirely recycled and repurposed for similar bonding needs.

Transmission and Reflection Properties of Iron Pyrite-Epoxy Resin Composite for Electromagnetic Applications.

This study examines the electromagnetic properties of a composite material composed of iron pyrite (FeS2) and epoxy resin, mixed in a 3:2 weight ratio to create a 10 cm3 cube. The research analyzes transmission and reflection coefficients and band gap parameters to determine its viability as an antenna substrate for electromagnetic wave applications. The composite displays a tunable band gap of 1.3 eV, enabling selective absorption and emission of electromagnetic radiation. The transmission coefficient achieved 90% throughout a frequency range of 1 GHz to 15 GHz, whilst the reflection coefficient was measured at 10%, significantly reducing reflecting losses. The epoxy resin binder was essential for preserving structural integrity and augmenting the dielectric characteristics of the composite, thereby raising transmission efficiency. UV-Vis spectroscopy showed an absorption value of 0.875% at the band gap, indicating efficient interaction with UV energy. The S21 transmission coefficient ranged from -10 dB to -80 dB, with a maximum of -40 dB at 6 GHz, indicating strong energy transfer capability for antenna applications. The S21 values exhibited negligible signal attenuation between 2 GHz and 7 GHz, indicating the material's exceptional suitability for antenna substrates necessitating dependable transmission. The S11 reflection coefficient varied from -5 dB to -55 dB, with substantial decreases between 4 GHz and 14 GHz, when reflection decreased to -45 dB, signifying little signal reflection at essential frequencies. The results underscore the composite's appropriateness for applications requiring high transmission efficiency, little reflection, and effective engagement with electromagnetic waves, especially as an antenna substrate. Measurements were performed using a vector network analyzer (VNA) to obtain the S11 and S21 characteristics, underscoring the material's potential in sophisticated electromagnetic applications.

Also, it was found that thermal transport is enhanced close to the solid boundary wall slip, leading to an improve heat distribution rate. Hence, this study contributes to the interplay complexity between external stimuli, fluid dynamics, and nanoparticle morphology in thermal systems, offering insights into the advanced materials synthesis, thermal management systems, and optimization and design of nanoparticle fluid enhancement applications.

Novel Structures for PV Solar Cells: Fabrication of Cu/Cu2S-MWCNTs 1D-Hybrid Nanocomposite.

The production of cost-effective novel materials for PV solar cells with long-term stability, high energy conversion efficiency, enhanced photon absorption, and easy electron transport has stimulated great interest in the research community over the last decades. In the presented work, Cu/Cu2S-MWCNTs nanocomposites were produced and analyzed in the framework of potential applications for PV solar cells. Firstly, the surface of the produced one-dimensional Cu was covered by Cu2S nanoflake. XRD data prove the formation of both Cu and Cu2S structures. The length and diameter of the one-dimensional Cu wire were 5-15 µm and 80-200 nm, respectively. The thickness of the Cu2S nanoflake layer on the surface of the Cu was up to 100 nm. In addition, the Cu/Cu2S system was enriched with MWCNTs. MWCNs with a diameter of 50 nm interact by forming a conductive network around the Cu/Cu2S system and facilitate quick electron transport. Raman spectra also prove good interfacial coupling between the Cu/Cu2S system and MWCNTs, which is crucial for charge separation and electron transfer in PV solar cells. Furthermore, UV studies show that Cu/Cu2S-MWCNTs nanocomposites have a wide absorption band. Thus, MWCNTs, Cu, and Cu2S exhibit an intense absorption spectrum at 260 nm, 590 nm, and 972 nm, respectively. With a broad absorption band spanning the visible-infrared spectrum, the Cu/Cu2S-MWCNTs combination can significantly boost PV solar cells' power conversion efficiency. Furthermore, UV research demonstrates that the plasmonic character of the material is altered fundamentally when CuS covers the Cu surface. Additionally, MWCN-Cu/Cu2S nanocomposite exhibits hybrid plasmonic phenomena. The bandgap of Cu/Cu2S NWs was found to be approximately 1.3 eV. Regarding electron transfer and electromagnetic radiation absorption, the collective oscillations in plasmonic metal-p-type semiconductor-conductor MWCNT contacts can thus greatly increase energy conversion efficiency. The Cu/Cu2S-MWCNTs nanocomposite is therefore a promising new material for PV solar cell application.

Electrical and dielectric properties of PVA-doped NiGdxFe2-xO4 nanoferrite particles

NiGdxFe2-xO4 nanoferrites combined with polyvinyl alcohol (PVA) and having a distinct spinel phase composition (x = 0.01, 0.03, 0.05, 0.07, and 0.09) were effectively created. Several characterization approaches were used to study the structural, dielectric, and magnetic properties of the PVA-blended nanoferrites. The acquired X-ray diffraction pattern showed the spinel cubic structure. Crystallite sizes of 50, 44, 40, 35, and 31 nm were found in PVA-blended nanoparticles for x = 0.01, 0.03, 0.05, 0.07, and 0.09, respectively. When compared to the PVA-unblended nanoferrites, the PVA-blended nanoferrites showed insulating properties with an enlarged energy bandgap. Real and complex dielectric constants, as well as the measured dielectric loss, were all in the microwave range (frequency ∼ 1.88–5.93 GHz). At higher frequencies, the dielectric constant became constant after declining with frequency. From the PVA-blended nanoferrites impedance study, pseudocapacitance (x = 0.01, 0.03, and 0.05) and resistive behavior (x = 0.07 and 0.09) were investigated. The magnetization hysteresis plot of PVA-blended NiGdxFe2-xO4 nanoferrites revealed a mild ferromagnetic character. The PVA doping of the produced nanoferrites increased their saturation magnetization and had a considerable microwave absorption capacity. For the broadest range of electromagnetic radiation absorption, ferrite might be the perfect material. The addition of rare-earth ions to these basic ferrites results in a considerable modification of the ferrites’ electromagnetic characteristics.

Dynamically Controllable Terahertz Electromagnetic Interference Shielding by Small Polaron Responses in Dirac Semimetal PdTe2 Thin Films

AbstractTerahertz (THz) electromagnetic interference (EMI) shielding materials is crucial for ensuring THz electromagnetic protection and information confidentiality technology. Here, it is demonstrated that high electrical conductivity and strong absorption of THz electromagnetic radiation by type‐II Dirac semimetal PdTe2 film make it a promising material for EMI shielding. Compared to MXene film, a commonly used metallic 2D material, the PdTe2 film demonstrates a remarkable 40.36% increase in average EMI shielding efficiency per unit thickness within a broadband THz frequency range. Furthermore, it is demonstrated that a photoinduced long life‐time THz transparency in Dirac semimetal PdTe2 films is attributed to the formation of small polarons due to the strong electron‐phonon coupling. A 15 nm‐thick PdTe2 film exhibits a photoinduced change of EMI SE of 1.1 dB, a value exceeding three times that measured on MXene film with a similar pump fluence. This work provides insights into the fundamental photocarrier properties in type‐II Dirac semimetals that are essential for designing advanced THz optoelectronic devices.

Momentary analysis of the electromagnetic radiation of gabbro rock under compressive stress

The phenomenon of electromagnetic radiation resulting from the application of pressure to rocks is caused by physical and chemical processes. Applying uniaxial pressure on gabbro rocks breaks the peroxy bonds and produces electron-hole pairs. These holes flow in the volume of gabbro rock under pressure and cause changes in electric charge, and as a result, generate variable electric and magnetic fields that vary with time and create electromagnetic signal. In this research work, by measuring the electric current of gabbro rock under pressure, its Fourier function is extracted, and the equations of the electric and magnetic fields of the sample and the energy and radiation equations of electromagnetic waves are calculated. Also, the relationship between these equations and the electric current equation is expressed. In addition, the amounts of absorption, transmission, and reflection of electromagnetic radiation of the rock can be analyzed during the application of pressure using the diagram of the radiant power of electromagnetic signal. The study of electromagnetic radiation can be useful for the development of electromagnetic radiation technology, can provide early warning about the risk of rock falls, and can reduce human injuries caused by the fall of places such as mines and tunnels.

Dielectric loss due to charged-defect acoustic phonon emission

The coherence times of state-of-the-art superconducting qubits are limited by bulk dielectric loss, yet the microscopic mechanism leading to this loss is unclear. Here, we propose that the experimentally observed loss can be attributed to the presence of charged defects that enable the absorption of electromagnetic radiation by the emission of acoustic phonons. Our explicit derivation of the absorption coefficient for this mechanism allows us to derive a loss tangent of 7.2 × 10−9 for Al2O3, in good agreement with recent high-precision measurements [Read et al., Phys. Rev. Appl. 19, 034064 (2023)]. We also find that for temperatures well below ∼0.2 K, the loss should be independent of temperature, which is also in agreement with observations. Our investigations show that the loss per defect depends mainly on properties of the host material, and a high-throughput search suggests that diamond, cubic BN, AlN, and SiC are optimal in this respect.

Elastic self-adhesive radioabsorbing materials

The article considers creation of elastic self-adhesive radio absorbing materials for frequency range of 2-7 GHz. Carbonyl iron is widely used in the production of radioabsorbing materials. Materials with this filler have a low absorption of electromagnetic radiation, and more reflect it. The main advantage of this filler is that it is produced by domestic manufacturers in industrial volumes. Another filler used for the production of radioabsorbing materials is carbon fibre. Materials on this filler have a high absorption coefficient of electromagnetic radiation, but operate in a very narrow frequency range. Therefore, in order to increase electromagnetic absorption and extend the frequency range, a certain amount of carbon fibre is introduced into the composition of the radioabsorbing material containing carbonyl iron. It is shown that in this case absorption of electromagnetic radiation reaches 93%. The material is intended for protection of premises and equipment against electromagnetic radiation.

Absorption of 5G sub-6 GHz electromagnetic radiation from base station to male reproduction system

Background The impact of electromagnetic radiation from communication on the male reproductive system has emerged as a significant concern in public health. A notable distinction of the 5G sub-6 GHz band, compared to traditional 2G, 3G, and 4G frequency bands, is the inclusion of higher frequency bands. This has raised public concerns regarding the potential effects of these higher frequencies on organisms, particularly their reproductive systems. While it is imperative to investigate the biological effects and potential risks associated with these new frequency bands in laboratory settings, comparing and evaluating differences between various frequency bands remain challenging due to the absence of standardized parameters such as exposure conditions and duration. In contrast, dose assessment offers a simpler and more reliable approach. Materials and methods The dose assessment method was employed in this study to investigate the risks associated with sub-6 GHz electromagnetic radiation from 5G base stations on the male reproductive system. A classical human body model (Duke) was utilized, and an electromagnetic simulation environment was established based on the actual polarization direction of the exposed base stations and various body postures. This research explored the effects of field direction, posture, public population, and frequency on the specific absorption rate of the reproductive system. Results and conclusions While maintaining the same level of exposure, a higher frequency results in a reduced dosage on reproductive system. Further analysis reveals that, considering the public exposure threshold, the employment of higher frequency bands in 5G sub-6 GHz does not present a greater dosage on reproductive system compared to lower frequency bands. Consequently, with regard to dosage, there is no need for excessive concern among the general public regarding the impact of electromagnetic radiation emitted by 5G base stations operating below 6 GHz on male reproductive health.

Внезонное поглощение электромагнитного излучения электронами с оптическим фононным участием в сверхрешетках квантовых точек

Physics Institute of Azerbaijan National Academy of Sciences In this paper, we investigate the absorption of electromagnetic radiation by a free electron gas interacting with lattice vibrations in a quantum dot superlattice. It is assumed that the electron gas in the quantum dot superlattice is limited by the anisotropic parabolic potential. The absorption of light by free carriers with the participation of phonons is calculated in the second order of the perturbation theory. When calculating the absorption coefficient, the matrix elements of the electron-photon and electron-phonon interactions (with polar and nonpolar optical phonons) are used. We can expect three possible transitions in the absorption coefficient for electron-polar phonon scattering: (1) a transition due to the size subband levels for only the x direction, (2) a transition due to the size subband levels for only the y direction and (3) a transition due to the size subband levels for both the x direction and the y direction. For electron-nonpolar phonon scattering we can expect оnly one possible transitions in the, the absorption coefficient: a transition due to the size subband levels for both the x direction and the y direction.

Charcoal-containing microwave electromagnetic radiation absorbers with relief surface

A new technology for manufacturing microwave electromagnetic radiation (EMR) absorbers characterized by a geometrically inhomogeneous surface is presented. The novelty of the presented technology lies in the use of radiotransparent polymer forms with hemispherical depressions of the same volume, which are the component for the formation of the surface layer of absorbers. The technology consists in filling these molds with a mixture of powdered activated (birch) charcoal and the binder in the liquid phase and further drying it in the forms. Compared with analogues, the developed technology is characterized by low complexity of reproduction. Most of the time required to implement the presented technology is associated with the drying process of a mixture of powdered activated birch charcoal and a binder. The experimentally established patterns of changes in the values of electromagnetic radiation reflection and absorption coefficients in the frequency range 1.0–28.0 GHz of the absorbers manufactured in accordance with the presented technology are provided, depending on the type of binder contained in them (polyvinyl acetate aqueous solution, gypsum aqueous solution, polyurethane mastic). It was determined that the most effective of the EMR absorbers studied in the course of establishing the indicated patterns are those ones that contain an aqueous solution of polyvinyl acetate. Electromagnetic radiation absorption coefficient values in the frequency range 1.0–28.0 GHz of such absorbers vary from 0.75 to 0.99. In addition, the mass per unit area of such absorbers is 1.5–2.0 times less than the mass per unit area of absorbers containing an gypsum aqueous solution or polyurethane mastic. Microwave EMR absorbers manufactured using the presented technology are characterized by higher mechanical strength, as well as lower cost compared to analogues and are recommended for use in the creation of anechoic chambers.

MICROWAVE ABSORBERS BASED ON MÖBIUS STRIP RESONATORS

The paper deals with technology of manufacturing of microwave absorbers with ordered and structured surface layer. This layer contains Möbius strip resonators, located on the fixed distance from each other. The technology was developed by the authors on the base of the following data: 1) results of theoretical study of microwaves interaction with Möbius strip resonator; 2) results of experimental study of electromagnetic radiation reflection, transmission and absorption coefficients in the microwave frequency range of the experimental samples of microwave absorbers based on Möbius strip resonators, which differ by the distance between these resonators. It was established on the base to the listed results that the microwave absorbers manufactured in accordance to the technology proposed by the authors are wide-band ones. Electromagnetic radiation absorption coefficient values of these absorbers changes from 0.5 to 0.97 in frequency range 2.0–17.0 GHz if the distance between the Möbius strip resonators containing in their surface layer, is 15.0 mm. If the distance between the Möbius strip resonators containing in the surface layer of the considered absorbers is less than 15.0 mm their electromagnetic radiation absorption coefficient in the indicated frequency bands is lower than presented values. The considered absorbers are promising for use in shielded rooms and anechoic chambers.

An Integrated Approach for Piezo-Electrochemical Nanoenergy Generation, Storage, and Real-Time Electromagnetic Interference Shielding Control.

The extensive utilization of high-end wireless electronic equipment in medical, robotics, satellite, and military communications has created a pressing challenge for real-time electromagnetic interference (EMI) control. Herein, a piezo-powered self-chargeable supercapacitor (PPSC) architecture based on an iron-doped graphitic nitride (Fe-g-C3N4: FGN) electrode with a solid piezoelectrolyte is devised, which can provide real-time controlled EMI shielding through piezo-powered self-charging voltage (SCV). This PPSC device along with real-time SCV-controlled EMI shielding also integrates additional features like nanoenergy generation and storing capability. The results demonstrate that the PPSC device is capable of exhibiting a piezo-tuned self-charging ability of up to 669.2 mV under 9.47 N of dynamic pressing for 180 s. The SCV electrostatically modifies the PPSC device that causes destructive interference and governs the absorption of electromagnetic radiation (EMR) and controls the absorption-dominated EMI shielding up to 59.2 dB at 500 mV. Additionally, the SCV-led electrification of the PPSC device also controls a unique functional transition from the EMR reflector to the EMR absorber at ∼90 mV. Hence, this strategy of tailored absorption and reflection adjustments of EMR could also potentially contribute toward the advancement of stealth technology for military armaments with externally controlled stealth capabilities.
