Abstract

3D electromagnetic simulation is used to study generator on a virtual cathode with feedback (FB). Implementation of FB through the input cavity in a double-stream mode provides premodulation of an electron beam that magnifies the overall performance of the device. The electromagnetic FB between input and output cavities provides changing of the intensity and frequency structure of oscillations of the vircator. Under certain conditions chaotization and amplification of HF oscillations induced in the output cavity is possible.
