Abstract

Abstract

A C-band resonant relativistic backward-wave oscillator(RBWO) is designed, and its structure feature and operation mechanism are analyzed. Operation characteristics of the designed device were investigated by particle-in-cell(PIC) simulation. Simulation results indicate that both the length of the insert and the radius of the reflector influence the power efficiency of the device. With the diode voltage ranging from 500 kV to 1 MV, the efficiency of designed device remains 20%~25%, while the generated microwave frequency keeps around 4.25 GHz. Furthermore, according to the analysis on the electrodynamics characteristics of the device, the longitudinal resonant modes and corresponding quality factors are studied with emphasis, which reveals that the device has a high efficiency with operati
