Briefing of Research Projects in Electromagnetics

Abstract

This presentation provides a brief overview of the research in Electromagnetics I have conducted over the past twenty five years. Included is early RCS Research with Ceramics and Thin Films, Relativistic Klystron Research, Antenna Measurement Technology Research and Research on Measurements of the Inosphere.

Ceramics and Thin Films
