High-Power Microwave Breakdown of Dielectric Interfaces

Abstract

This is the final technical report for AFOSR Grant No. 91-0260, that began in May, 1991 and concluded two years later on May 15, 1993. The first objective of this project was to study the electrical breakdown, due to microwaves, which occurs on the surface of vacuum/atmosphere interfaces. This part of the contract was continuing work started on AFOSR Grant No. 88-102. The second objective of the project was to begin the development of a coaxial vircator. Most of the breakdown results were reported in the previous annual technical report and will only be mentioned briefly. One particular window was tested during the last year of the contract and its results will be detailed in this report. Extensive simulations have been conducted on the coaxial vircator geometry with surprising results. AH of the results from the coaxial vircator simulations are given in this report.
