| 摘 要： | 为抑制回旋行波管的自激振荡和增加回旋行波管带宽,俄罗斯G.Denisov等人提出一种新型回旋行波管结构——螺旋波纹波导回旋行波管。通过螺旋波纹波导的特殊结构使通过波导的两种模式发生耦合,耦合出一种新的工作模式,从而改变色散特性,达到抑制自激振荡和增加带宽的目的。通过螺旋波纹波导的色散方程,分析其色散曲线,从而分析螺旋波纹波导作为回旋行波管高频系统的优势。

| Abstract: | In order to restrain self-oscillation and increase bandwidth of gyro-TWT,G.Denisov and his colleague advanced a new gyro-TWT with a helical operating waveguide.By the special structure of gyro-TWT with helical operating waveguide,two kinds of modes coupling a new work mode when they through the spiral waveguide to change the dispersion and to restrain self-oscillation and increase bandwidth.The dispersion curve is analyzed through the dispersion equation,and the advantages of spiral waveguide as the high-frequency system of gyro-TWT are discussed. |
