IEM Distinguished Lecturers Seminar: Reconfigurable intelligent surfaces for extending the limits of wireless communications
***Coffee and cookies will be served at 13:00 in the hall of BM 5202***
Abstract
The upcoming 6G pushes the 5G performance indicators to unprecedented levels, envisioning up to THz frequencies, devices with embedded sensing capabilities, and native artificial intelligence. These challenging features are expected to become a reality around 2030 under a green and trustworthy network paradigm. In this talk, we will elaborate around the emerging technology of reconfigurable intelligent surfaces, its efficient configuration optimization via state-of-the-art multi-functional hardware architectures. We will discuss recent results on the capacity characterization of the multi-RIS-empowered MIMO MAC as well as a novel framework for over-the-air edge inference with multi-functional RISs acting as layers of a wireless-communications-centric artificial neural network.

George C. Alexandropoulos received the Engineering Diploma (Integrated M.S.c), M.A.Sc., and Ph.D. degrees in Computer Engineering and Informatics from the School of Engineering, University of Patras, Greece in 2003, 2005, and 2010, respectively. He has held senior research positions at various Greek universities and research institutes, and he was a Senior Research Engineer and a Principal Researcher at the Mathematical and Algorithmic Sciences Lab, Paris Research Center, Huawei Technologies France, and at the Technology Innovation Institute, Abu Dhabi, United Arab Emirates, respectively. He is currently an Associate Professor with the Department of Informatics and Telecommunications, School of Sciences, National and Kapodistrian University of Athens (NKUA), Greece and an Adjunct Professor with the Department of Electrical and Computer Engineering, University of Illinois Chicago, Chicago, IL, USA. His research interests span the general areas of algorithmic design and performance analysis for wireless networks with emphasis on multi-antenna transceiver hardware architectures, full duplex radios, active and passive Reconfigurable Intelligent Surfaces (RISs), Integrated Sensing And Communications (ISAC), millimeter wave and THz communications, as well as distributed machine learning algorithms. He currently serves as an Editor for IEEE Transactions on Communications, IEEE Transactions on Green Communications and Networking, IEEE Wireless Communications Letters, Frontiers in Communications and Networks, and the ITU Journal on Future and Evolving Technologies. Prof. Alexandropoulos is a Senior Member of the IEEE Communications, Signal Processing, Vehicular Technology, and Information Theory Societies, the Chair of the EURASIP Technical Area Committee on Signal Processing for Communications and Networking, as well as a registered Professional Engineer of the Technical Chamber of Greece. He is also a Distinguished Lecturer of the IEEE Communications Society. He has participated and/or technically managed more than 15 European Union, international, and Greek research, innovation, and development projects, including the H2020 RISE‑6G, SNS JU TERRAMETA, SNS JU 6G-DISAC, and ESA PRISM projects dealing with RIS-empowered smart wireless environments, THz RISs, distributed ISAC, and RIS demonstration for localization and mapping, respectively. He has received the best Ph.D. thesis award 2010, the IEEE Communications Society Best Young Professional in Industry Award 2018, the EURASIP Best Paper Award of the Journal on Wireless Communications and Networking 2021, the IEEE Marconi Prize Paper Award in Wireless Communications 2021, the Best Paper Award from the IEEE GLOBECOM 2021, the IEEE Communications Society Fred Ellersick Prizes 2023 and 2024, and the IEEE Communications Society Leonard G. Abraham Prize 2024.
