摘　　要：文章从理论上分析了多注行波管耦合阻抗原理,利用自行研制的数值软件建立了多注行波管慢波结构模型,模拟了多注慢波耦合特性,得到耦合阻抗曲线,并分析了相关参数对多注行波管耦合阻抗的影响;最后得出结论,多注行波管耦合阻抗较大,故其波注互作用效果明显,增益较高。The principle of coupling impedance of multi-beam traveling wave tubes is analyzed theoretically. With self-designed numerical software, the model of slow wave structure of multi-beam traveling wave tubes is established, the coupling impedance curve obtained, and some parameters which affect the coupling impedance of multi-beam traveling wave tubes are analyzed. It is concluded that the plus of multi-beam traveling wave tubes is high and the interaction effect of beam-wave is good because of high coupling impedance.
