Title: Science of Electronics in Extreme EM Environments: AFRL/AFOSR Center Activities*

Abstract: Researchers and students at the University of Maryland are engaged in a number of basic studies relevant to the interactions between microwave radiation and electronic equipment as part of the collaborative Center of Excellence sponsored by AFOSR and AFRL. This talk will review these briefly. Broad areas include: basic mathematical characterization of field distributions in systems, measurement of EM coupling in different topologies, and effect of microwave radiation on future semiconductor and optoelectronics devices. Within these broad areas the following specific studies may be highlighted: a) distribution of electromagnetic wave energy on networks, b) statistics of fields in systems with both regular and chaotic ray trajectories, c) using computational electromagnetics codes to determine Random Coupling Model parameters, d) extracting model parameters from complex systems, e) experiments on field distributions in scaled geometries, f) application of density functional theory to determine the effect of radiation and defects on characteristics of a new class of FETs, and g) effects in high-performance photonic interconnects based on novel 2D materials.

Biographical Sketch of Thomas M. Antonsen Jr.

Thomas M. Antonsen Jr. was born in Hackensack, New Jersey in 1950. He received his Bachelor’s degree in electrical engineering in 1973, and his Master’s and Ph. D. degrees in 1976 and 1977, all from Cornell University. He was a National Research Council Post Doctoral Fellow at the Naval Research Laboratory in 1976-1977, and a Research Scientist in the Research Laboratory of Electronics at MIT from 1977 to 1980. In 1980 he moved to the University of Maryland where he joined the faculty of the departments of Electrical Engineering and Physics in 1984. He is currently Professor of Physics and the Electrical and Computer Engineering Professor of Electrophysics. Professor Antonsen has held visiting appointments at the Institute for Theoretical Physics (U.C.S.B.), the Ecole Polytechnique Federale de Lausanne, Switzerland, and the Institute de Physique Theorique, Ecole Polytechnique, Palaiseau, France. He served as the acting director of the Institute for Plasma Research at the University of Maryland from 1998 to 2000. He was selected as a Fellow of the Division of Plasma Physics of the American Physical Society in 1986, and fellow of the IEEE in 2011. In 1999 he was a co-recipient of the Robert L. Woods award for Excellence in Vacuum Electronics Technology, and in 2003 he received the IEEE Plasma Science and Applications Award. In 2004 Professor Antonsen was given the Outstanding Faculty Research Award of the Clark School of Engineering. In 2010 he served as Chair of the Division of Plasma Physics of the American Physical Society. He received the IEEE J.R. Pierce Award for contributions to vacuum electronics in 2016.

Professor Antonsen’s Research interests include the theory of magnetically confined plasmas, the theory and design of high power sources of coherent radiation, nonlinear dynamics in fluids, and the theory of the interaction of intense laser pulses and plasmas. He is the author and coauthor of over 350 journal articles and co-author of the book “Principles of Free-electron Lasers”. Professor Antonsen has served on the editorial board of Physical Review Letters, The Physics of Fluids, and Comments on Plasma Physics.
