virtual cathode oscillator overview

Abstract

The first high power microwave (HPM) pulse created by the man was produced during the first atomic bomb test; after that, HPM has been of special interest to military research and recently to the industry. Virtual Cathode Oscillator (Vircator) is a type of HPM source. The Vircator offers a great amount of be- nefits compared to other HPM sources. This essay will provide an overview of Virtual Cathode Oscillator, its evolution; its functionally, and it will serve as a starting point to study it.
