Thomas M. Antonsen, Jr.


ResearchPublications



Thomas M. Antonsen, Jr. was born in Hackensack, New Jersey, in 1950. He received his B.S. degree in electrical engineering in 1973, and his M.S. and Ph.D. degrees in 1976 and 1977, all from Cornell University. He was a National Research Council postdoctoral 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 currently holds a joint academic appointment as Professor of Physics and Professor of Electrical Engineering; his research is in the Institute of Research for Electronics and Applied Physics. Prof. Antonsen has held visiting appointments at the Institute for Theoretical Physics (UCSB), the Ecole Polytechnique Federale de Lausanne, Switzerland, and the Institute de Physique Theorique, Ecole Polytechnique, Palaiseau, France. He was selected as a Fellow of the Division of Plasma Physics of the American Physical Society in 1986.


Research

Prof. 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 or co-author of over 140 journal articles and co-author of the book "Principles of Free-electron Lasers." Prof. Antonsen has served on the editorial board of Physical Review Letters, The Physics of Fluids, and Comments on Plasma Physics.
