摘　　要：通过仿真计算对平顶型正弦波导的慢波特性进行了分析研究,提出了一种可用于W波段大功率行波管的两段式平顶型正弦波导高频电磁系统,并完成了输入输出结构和集中衰减器的优化设计;利用粒子模拟方法获得了带状电子注与此结构中慢电磁波注—波互作用特性,计算结果表明该行波管在92~101 GHz的频率范围内可获得200 W以上的输出功率,增益大于30 d B.The slow wave characteristics of truncated sine waveguide are analyzed by the simulation method.The two-section high frequency electromagnetic system based on truncated sine waveguide(TSWG)is proposed,which can be used for the W-band Traveling Wave Tube(TWT).Meanwhile,the input/output coupler and attenuator are designed for the high frequency system.We obtain the beam-wave interaction results in the high frequency electromagnetic system by the Particle-in-cell(PIC)simulation method.The PIC simulation results indicate that the TWT can produce the output power over 200 W and gain over 30 dB in the frequency range of 92~101 GHz.
