Title: A high-efficiency relativistic magnetron with the filled dielectric

Abstract

Relativistic magnetron (RM) is a popular high power microwave device. Filling the resonant cavities with the low-loss dielectric is a well-proven technology that improves the performance of RM. In order to enhance the power efficiency, a dielectric-filled relativistic magnetron (DFRM) is presented and investigated numerically with KARAT code in this paper. The simulation results indicate that the maximum power efficiency is enhanced from 50.0% in the conventional RM to 56.0% in the DFRM when the applied voltage and the magnetic field are 280 kV and 0.5 T, respectively. Besides, the simulation results are analyzed and discussed.
