Abstract :
The study of the output power of electromagnetic radiation of a relativistic electron beam (REB) with a virtual cathode in the presence of external magnetic field has been carried out. The typical dependencies of the output microwave power of the vircator versus external magnetic field have been analyzed by means of 3D electromagnetic simulation. It has been shown that power of the vircator demonstrates several maxima with external magnetic field growth. The characteristic features of the power behavior are determined by the conditions of the virtual cathode formation in the presence of the external transversal magnetic field and the REB self-magnetic fields.
