摘　　要：螺旋波纹波导的特殊结构使TE11和TE21相互耦合,其色散特性相对于圆波导发生了极大地改变,使电磁波能够在宽频带内与电子注耦合,因此需要对其色散特性进行研究。通过研究Ka波段螺旋波纹波导回旋行波管的冷腔色散特性,可知螺旋波纹波导非常适用于回旋行波管的高频结构。由电子运动方程出发,推导出了简化的螺旋波纹波导回旋行波管的注波互作用方程。Helical operating waveguide makes TE11 and TE21 couple because of its special structure,its dispersion characteristic has changed compared with circular waveguide,this dispersion characteristic makes the magnetic wave and the electron beam couple in the broad frequency band, so its dispersion characteristic need to be researched. Through studying the dispersion characteristics of Ka band gyro-twt with a helical waveguide, the result s showed that the helically grooved waveguide is a most favorable interaction structure for gyro-twt. The simplified beam-wave interaction dispersions equation of gyro-twt with a helical waveguide was obtained from the beam-wave interaction equations.
