Dr. Anagnostou is currently supported by a prestigious H2020 Marie Skłodowska-Curie Individual Fellowship on wireless sensing technologies (ViSion-RF). He has authored or co-authored more than 160 publications (h-index 28; more than 3000 citations), two book chapters, and holds two U.S. patents. His interests include: antennas (reconfigurable, adaptive, miniaturized, space/satellite, and wearable), microwave circuits, radar sensing, phase-change materials (e.g. VO2) for reconfigurable devices, direct-write, MEMS, and applications of artificial neural networks in electromagnetics and health care.

Dr. Anagnostou serves or has served as an Associate Editor for the IEEE Transactions on Antennas and Propagation, IEEE Access, and IET Microwaves, Antennas and Propagation. He is a Guest Editor for IEEE Antennas and Wireless Propagation Letters and MDPI. He is a member of the IEEE AP-S Educational Committee and Vice Chair for online content. He received the 2010 IEEE John D. Kraus Antenna Award, the 2011 DARPA Young Faculty Award, the 2014 Campus Star Award by the ASEE, the 2017 Young Alumni Award by the University of New Mexico, the H2020 MSCA Fellowship, and 4 Honoured Faculty Awards. His students have also been recognized with IEEE and university awards.

#### **Michael Chryssomallis**

Michael T. Chryssomallis received his Diploma and the Ph.D. degree in Electrical Engineering from Democritus University of Thrace (DUTh) and he is a Professor in Electrical and Computer Engineering (ECU) Department in DUTh. Over recent years, he has taught/teaches undergraduate and graduate courses in Antennas, Telecommunications, Mobile Communications, Wave Propagation, and Electromagnetic Interferences and Immunity (EMC/EMI). He has supervised more that 80 diploma theses, 14 postgraduate theses and 2 PhDs (+2 in progress). He has participated in 17 research projects. Regarding his administrative work, he was elected as the Sector Director for 5 years, Deputy of Department Chair for 4 years and Director of Postgraduate Studies for 4 years.

He worked with the Communications Group (director Prof. P. S. Hall) of the University of Birmingham for the period of October 1997 to January 1998, in the areas of Active Antennas, and with the Wireless Group (director Prof. C. G. Christodoulou) of the University of New Mexico for the periods of April to June 2000, and April to July 2002, in the areas of Microstrip Antennas and Arrays, and Smart Antennas.

His current research interests are in the areas of microstrip antennas, small antennas, RF-Mems, smart antennas, algorithms of beamforming and angle of arrival estimation, and propagation channel characterization. He is the author or co-author of about 100 journal papers and conference proceedings (>1400 citations in Google Scholar and >850 in Scopus). He has translated an English technical book into Greek and has co-authored three chapters in Wiley Encyclopedias of Electrical and Electronic Engineering and RF/Microwave Engineering. He serves as a reviewer for several publications of IEEE, IEE and others. He has been a member of Greek Technical Chamber and of IEEE since 1988 (senior member since 2000).
