The advance of 5G to 6G will join communication and sensing systems (JCS) through wideband base-station, non-terrestrial networks (NTN) such as satellite communications (SATCOM), X-MIMO (eXtreme MIMO), STAR (simultaneous transmit and receive systems also known as self-duplex), and advanced automotive radar systems. Strong interest in techniques to extend systems from RF through microwave to 300 GHz. Systems and sub-systems based on narrowband and wideband low-power transceivers using advanced CMOS, SiGe, GaA and GaN technologies, analog and digital beamforming phased-arrays, active and passive reflect arrays (also known as RIS – reflect impedance surfaces), multi-channel automotive imaging radars, N-path receivers with linearity enhancement and IP3 cancellation, efficient power amplifiers with digital pre-distortion using AI/ML algorithms, to name a few, are being developed at a rapid pace. In addition, calibration and built-in-test of such complex chips and sub-systems reduce the calibration time and system cost. Also, several advanced systems can only be built using novel heterogeneous 3-D packaging capable of co-integrating different technologies in a low-loss and thermally-efficient module. RF/Microwave systems will continue to pervade our daily lives, with D-band and G-band systems coming soon for point-to-point communications and high-resolution radars.

Novel materials, processes and manufacturing technologies have emerged in recent years, which have shown great potential in the development of RF/microwave and wireless systems and applications. Over the last 20 years, there has been a growing interest in RF/microwave materials and fabrication techniques, which enable the creation and innovation of devices, microwave circuits and systems over MHz-through-THz. This Special Issue on Emerging Materials and Processing Technologies for RF/Microwave and Wireless Systems and Applications is to promote this area by providing excellent opportunities for cross-disciplinary researchers and practitioners to share the recent progress on microwave materials and fabrication techniques.

The scope of this T-MTT Special Issue includes emerging RF/microwave materials and fabrication processes, which should present significant potential in advancing future RF, microwave, millimeter-wave, terahertz devices, circuits, and systems. This cross-disciplinary area brings together researchers, scientists, and engineers of different backgrounds to promote and exploit emerging and novel materials, processes, and manufacturing techniques. This also provides opportunities for the MTT-S community to share cross-disciplinary R&D activities and outcomes. Publishable manuscripts may include but not be limited to material engineering, chemical engineering, photonics/optical engineering, mechanical engineering and process engineering.

Contactless radar-based physiological sensors have become a topic of great interest in the last decade, enabled by recent hardware advances for automotive radar and next generation communications systems, and driven by a variety of healthcare, industrial, and security applications. Hardware advances include higher levels of transceiver integration with faster ADCs, more powerful processing, as well as integrated antennas and MIMO and beam steering capabilities. The need for unobtrusive monitoring is being driven by an aging population, higher levels of automation (IoT, UAV), development of smart environments, and NextG communications systems.

Automotive radar development has made millimeter-wave radar hardware readily available, operating in the ISM bands from 24 GHz to over 240 GHz, and including MIMO/beam steering capability. As automotive radar development grows to incorporate in-cabin monitoring, related hardware has become available for a number of other applications including perimeter security, vital signs health monitoring, occupancy sensing, and UAV-based monitoring. The emerging 6G communications standard will incorporate joint communication and sensing (JCAS), and more opportunities for radar sensing with communications signals to further drive advancement of physiological radar.

As technological development for physiological radar continues to grow, many fundamental questions remain: What is actually being measured? What are the optimum waveforms and operating frequencies for different applications? What are the fundamental limitations on radar sensitivity? What are the most useful metrics for assessing accuracy and benchmarking performance? What can be considered motion of interest and to what extent can it be isolated from extraneous motion?

This Special Issue solicits papers that report of the latest advancements in radar-based physiological sensors.
