PROFESSOR DIAMENT

Professor Diament joined the E.E. faculty in 1963. His teaching and research areas are in all phases of electromagnetics and wave propagation, including microwaves, antennas, optics, radiation statistics, plasmas, wave interactions, relativistic electron beams, and transient electromagnetic phenomena. He is the author of Wave Transmission and Fiber Optics, published in 1990 by Macmillan, and of Dynamic Electromagnetics, published in 2000 by Prentice Hall.

Professor Diament’s current interests include: Antennas for satellite communications, fiber optics, waveguiding in VLSI chips, electromagnetics and free electron lasers.
