摘    要:An axially extracted virtual cathode oscillator(vircator)with a feedback annulus is proposed and configured through particle-in-cell simulation.This compact device needs no guiding magnetic field.Its experimentally radiated microwave is measured to be of quasi-single TM01 mode with a frequency range of 4.41-4.69GHz and a power level of above 300MW,when the diode voltage ranges between 400-480kV and the beam current 20-25kA;this confirms the simulation results.

关 键 词:阴极振荡器  大功率微波器件  反馈环
