Dr. Dimitrios V. Peponis was born in Athens in 1987. He received his B.Sc. in Physics from the Department of Physics of the National and Kapodistrian University of Athens (NKUA) in 2011, and in 2014 he obtained his M.Sc. degree in Electronics and Radioelectronics from the Departments of Physics and Informatics & Telecommunications of NKUA. In 2020, he was awarded a Ph.D. in Physical Sciences from the Department of Physics of NKUA, with his dissertation entitled “Study of beam–wave interaction in complex waveguide structures.”
Since 2011, he has been a member of the Microwave and Optical Applications Research Group of the Department of Physics at NKUA, focusing on the development of numerical codes for solving complex electromagnetic problems. He participates as a researcher in the European EUROfusion program, working on the study, design, and simulation of high-frequency, high-power microwave sources for applications in controlled nuclear fusion.
He has also served as an adjunct lecturer at the Department of Electrical and Electronic Engineering Educators of ASPETE, where he taught laboratory courses in Telecommunication Systems, Optical Communications, and Measurements & Instrumentation.
He has published more than 13 papers in peer-reviewed international journals, 16 papers in conference proceedings, and 8 conference presentations.
His research interests include applied and computational electromagnetics, the development of numerical codes for solving complex electromagnetic and electrodynamic problems, high-frequency and high-power microwave tubes, as well as fusion technology.
