Abstract

Space-based solar power has been in discussion for the last 40 years at least, but recently, with technological advances and the increase in gas cost, this topic is on the table again, not only in academic environments but especially in governmental programs. Some of the countries investing significantly in this approach include USA, Japan, China, Canada, the UK, New Zealand, Australia, and more recently the EU. The concept implies collecting energy out in space and beaming it to where needed, been earth or any other planet and or satellite; one of the most recent ideas has been to use it to power up moon stations by creating a truly microwave energy link network on the moon. This special session's objective is to bring researchers in this area to IMS and to discuss the novelties in microwave transmitters and receivers, being those highly efficient power amplifiers or high efficient RF to DC converters.

Abstract

Future 6G wireless systems and beyond will support communications, sensing, and positioning at multiple spectrum bands. Novel networking architectures will be required to achieve performance, resiliency, and flexibility for deployment of the antenna and related radio frequency (RF) hardware on fixed locations and vehicles for the radio access network. Deployment of a massive number of low SWaP-C picocells for coverage and flexible locations is a complex challenge that will strain the conventional base station, microcell, and even the O-RAN architectures, especially when applied to mm-wave and sub-THz spectrum bands at > 100 GHz. Does analog photonic have a role in meeting these challenges? If so, what and what are the key bottlenecks to implementation? This focus session tackles this question and will feature diverse technical perspectives (all-electronic, digital photonic, analog photonic and hybrid) from academia, industry and government labs.

Abstract

Next-generation RF/mmW systems are of great interest in supporting high data rate communications, which include future 5G FR3 and millimeter-wave 5G FR2 and 6G mobile networks. These RF networks can potentially deliver 10 Gbps or higher and backhaul communications with > 50 Gbps. Since E/D/G-band can also support multi-GHz bandwidths, there is also growing interest in mmW phased-array implementations.

This focused session will cover emerging high-performance Silicon and III-V RF/mmW technologies toward 5G/6G wireless applications and DoD applications with speakers from both commercial (Global Foundries and Intel) and Defense (DARPA, Northrop Grumman, HRL) sectors.

Abstract

Dr. Atia was a long-time contributor to the MTT-S in various capacities. Since 1969 he has been involved in research and development of a broad range of advanced microwave technologies for communication satellite transponders and antennas. Dr. Atia had seminal and fundamental contributions in the field of microwave filter synthesis and he was the recipient of the Pioneer Award of the IEEE Microwave Theory and Techniques Society (IEEE MTT-S) in 1997.

Dr. Zaki was a long-time contributor to the MTT-S in various capacities as well. She was the first female to graduate with a Ph. D. in Electrical Engineering from the University of California, Berkeley, and the first female professor to join the department of Electrical and Computer Engineering at the University of Maryland, College Park. There she led an academic life of more than four decades. There she supervised many Ph. D. students and contributed enormously to the field of Electromagnetic modelling of passive components namely microwave filters and multiplexers. Her original research on Dielectric Resonators and filters was fundamental in advancing the state of the art in Dielectric Resonator filters.

Abstract

This memorial session will pay tribute to Professor John W. Bandler by recognizing his seminal contributions and visionary perspective on CAD techniques for RF and microwave modeling and automated design optimization. Invited outstanding collaborators will provide an overview of Prof. Bandler’s main technical achievements and contributions, combined with personal anecdotes and photos highlighting memorable events and interactions. Joint technical developments to be reviewed include analysis methods for the response sensitivities of microwave circuits, including efficient electromagnetics (EM)-based S-parameters sensitivity calculations for accurate design and image-reconstruction; the port‐tuning version of space mapping for efficient EM-based analysis and design; cognition-driven design for microwave filter optimization; advanced industrial microwave design problems in satellite systems; space mapping techniques for efficient post-manufacture tuning of microwave hardware; smart combination of artificial neural networks and space mapping for EM-based design optimization, statistical analysis, and yield optimization of microwave circuits; as well as interesting analogies between space mapping and artificial intelligence (AI) approaches. Potential future directions will also be ventured regarding the relationship between cognitive science and engineering design, involving promising deeper integration of artificial intelligence, machine learning, and space mapping.

Abstract

This session covers wave-material interactions ranging from microwave microscopy to high-power density plasma generation. Near-field microscopy for high-resolution material characterization at room and cryogenic temperatures is shown using frequencies from 2 to 12 GHz. Additionally, resonator-based field enhancement is shown for low-power plasma generation in the 2.45 GHz ISM band.
