摘　　要：设计了一种带有反射腔的能在X波段实现稳定双频输出的圆柱结构相对论返波管,采用2.5维相对论全电磁PIC粒子模拟软件行粒子模拟研究。仿真结果表明:在输入电压433 kV、引导磁场2.2 T的条件下,实现了9.53,10.09 GHz的双频稳定输出,平均输出功率340 MW,平均功率效率24.1%。A relativistic backward wave oscillator（RBWO） with resonant reflector has been designed to produce dual-frequency microwaves.The 2.5 dimensional fully electromagnetic simulation software was adopted to simulate the cylindrical RBWO.Dual-frequency microwave output of 9.53 and 10.09 GHz is obtained for the beam voltage of 433 kV and guiding magnetic field of 2.2 T.The average output power is 340 MW and the average power efficiency is 24.1%.
