| 摘 要： | 借鉴Khanh Nguyen提出的多束折叠波导行波管结构，设计出了可以有效抑制自激振荡的140GHz多束折叠波导行波管。利用PIC软件对双束微折叠波导行波管进行了仿真计算，并与单束模型进行了对比研究，结果表明行波管采用多束机制可以有效提高器件的增益，克服管子加工长度的困难,且有效抑制了管子的自激振荡。

| Abstract: | On the Basis of Khanh Nguyen’s multiple-beam FWG-TWT structure, the paper investigates the structure of 140 GHz multi-beam FWG-TWT, which can suppress the self-excited oscillation effectively. A lot of simulations have been done about the two-beam FWG-TWT. In comparison with one-beam model, the two-beam model can achieve higher power gain while the length is reduced and the self-excited oscillation is inhibited effectively. |
