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。 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.
