The Many Dimensions of the MTT Community [From the Editor’s Desk

The IEEE Microwave Theory and Technology Society (MTT-S) represents a diverse and inclusive community whose work spans components and systems from MHz to THz. These wide-ranging topical areas are organized into 26 technical committee (TCs) in technologies spanning from core technologies and applications to systems and applications. Each month, <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">IEEE Microwave Magazine</i> tries to bring you the best overview and review articles on representative aspects of these technology areas, whether they are technical features supplied by one of our TCs or technical features supplied by engineers working in a technical field. Periodically, we also report on work performed by students and young professionals, who are the next generation of MTT leaders. Finally, we act as a communications channel for MTT administrative bodies to talk to and, we hope, solicit comments from the members. If one is interested in components, circuits, or systems, from MHz to THz, MTT is the go-to community.

2022 Reviewers List

The availability of highly qualified reviewers is a fundamental part of the success of IEEE MICROWAVE AND WIRELESS TECHNOLOGY LETTERS as the leading compact-format publication in the broad field of Microwave Theory and Technology. In that sense, we must feel extremely proud and lucky about the high number of volunteering experts across the entire world who dedicate their efforts in a selfless way to provide their timely and rigorous review reports for papers assigned to them. Their priceless service is essential, not only by ethically judging and evaluating the technical impact and novelty of every submitted paper, but also by greatly enhancing their contents from the initial versions to the published ones through their very valuable comments and suggestions. Having internationally recognized reviewers from all the world has a clear positive impact on the final published papers, which are enriched by the wise advice of experts from different research cultures, viewpoints, and experiences, this being the basis of an high-quality peer-review process.

International Conference on Microwave Acoustics &amp; Mechanics [Conference Reports

After being postponed for two years, the inaugural edition of the IEEE Microwave Theory and Technology Society (MTT-S) International Conference on Microwave Acoustics & Mechanics (IC-MAM) was held from 18 to 20 July 2022 in the Training Center of Rohde & Schwarz in Munich, Germany. It was financially sponsored by the IEEE MTT-S (Figure 1) and technically cosponsored by the European Microwave Association.

Distinguished Microwave Lectures: An Enriching Experience for MTT-S Members and Speakers [Women in Microwaves

IEEE offers a Distinguished Lecturers Program, allowing Chapters to host distinguished lecturers who are excellent speakers and experts in their respective topical fields. Within the IEEE Microwave Theory and Technology Society (MTT-S), this program is renamed the Distinguished Microwave Lecturers (DMLs) Program. In the summer of 2022, the MTT-S announced the DML class for 2023–2025. We observed that this was the 10th all-male class since 2009. In fact, there have been only five female DMLs since the 2009 class, including the present two female DMLs. A major reason is the lack of nominations of female candidates. The same observation is valid in terms of geographical diversity. Therefore, this column elaborates on the nomination process and shares the experiences of female DMLs.

Aerospace Applications: Part 2 [From the Guest Editor’s Desk

Following the first focused issue sponsored by the IEEE Microwave Theory and Technology Society Technical Committee (TC) 29, published with its eye-catching cover in the October 2022 issue of this magazine <xref ref-type="bibr" rid="ref1" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[1]</xref> , we are pleased to bring to you two additional contributions related to aerospace applications. These two articles show again the broad range—from ground to space—of interesting developments covered by microwave aerospace systems and complement nicely the first set of contributions.

New Challenges for MTT Members—Increase the Value of Our Membership Worldwide [President’s Column

February is here, and the new conference, the International Microwave and Antennas Symposium (IMAS), will be one of the highlights of this month for our members. IMAS is the first African symposium focused on microwaves and antennas, and it will be the seed for a new enthusiastic and vibrant meeting place for our members ( <xref ref-type="fig" rid="fig1" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Figure 1</xref> ). The symposium is a collaboration between the IEEE Microwave Theory and Technology Society (MTT-S) and the Antennas and Propagation Society (AP-S).

Guest Editorial

This Special Issue of IEEE Transactions on Microwave Theory and Techniques (TMTT) is comprised of the extended papers from the 2022 IEEE Microwave Theory and Technology Society (IEEE MTT-S) International Microwave Symposium (IMS2022), held in Denver, CO, USA, in June 2022. The IEEE MTT-S International Microwave Symposium is the world’s major event on microwave technologies annually organized by the IEEE MTT-S as the society’s premier flagship conference. The conference represents a unique opportunity to bring together researchers and practitioners with diverse technical backgrounds to share the most recent advances in MHz-to-THz technologies and systems. After two years of the COVID-19 pandemic, IMS2022 came back to being an in-person-only event that was held on June 19–24, 2022, at the Colorado Convention Center, Denver.

Editorial

I am highly honored to have been appointed as Editor-in-Chief of the IEEE Transactions on Microwave Theory and Techniques (T-MTT) by the Administrative Committee of the IEEE MTT Society (MTT-S). It is a great privilege and responsibility to work for this prestigious journal with 70 years of history, which has published instrumental advances to the progress in communications, radar, radiometry, and other applications that we enjoy today. The present time is also full of exciting research challenges: on the 5th Generation and beyond, demanding power and spectral efficient massive access and reconfigurability; on the Internet of Things, demanding energy efficiency and sustainability, reliability, and low-cost; and in the continuous quest for a better performance of compact radar systems, nonintrusive medical monitoring, highly sensitive microwave sensors, microwave imaging systems, microwave photonics or microwave radiometry, to name just a few. There are also new fields, such as quantum computing that require microwave signals and methods. All this progress demands advances in devices, components, and systems, as well as in analysis, simulation, and characterization methodologies. We expect that IEEE T-MTT will continue to be the premier journal for the dissemination of all these ongoing and future research.

Guest Editorial

This Transactions on Microwave Theory and Techniques&’ Mini-Special Issue includes eight papers from the 2022 IEEE Radio and Wireless Week (RWW 2022) held in Las Vegas, NV, USA, January 16–19, 2022. The Radio and Wireless Week consists of five related conferences that focus on the intersection between wireless communication theory, systems, circuits, and device technologies: the Radio and Wireless Symposium (RWS), the Topical Conference on RF/Microwave Power Amplifiers for Radio and Wireless Applications (PAWR), the Topical Meetings on Silicon Monolithic Integrated Circuits in RF Systems (SiRF), the Topical Conference on Wireless Sensors and Sensor Networks (WiSNet), and the Space Hardware and Radio Conference (SHaRC). Radio and Wireless Week is thus a multidisciplinary event bringing together innovations that are happening across the broad wireless spectrum. A total of 185 papers were submitted to the RWW 2022 Technical Program Committee, of which 135 papers were accepted for presentation and publication online on the IEEE Xplore website. Together with the technical sessions, RWW 2022 successfully held seven workshops, a special focus session on massive MIMO beamforming technologies for 5G and beyond, a plenary presentation on topics related to artificial intelligence in circuit design and 6G, a dedicated track for the IEEE Distinguished Microwave Lecturers, and a demo track session to show the latest innovative wireless experimental achievements. For the second time, RWW had a live session on Distinguished Women in Microwaves bringing together a panel of women who have contributed to the microwave society for the last few years including high-quality talks in radio and wireless applications.
