摘　　要：计算了螺旋槽波导的色散特性和群速度,用"准周期边界条件"方法和谐振法模拟计算了螺旋槽波导的色散特性,两种方法的模拟结果与计算都比较一致。此外,还模拟测试了渐变与规则螺旋槽波导连接的匹配性能、螺旋槽波导高频系统的传输特性。结果表明,螺旋槽波导是非常适用于回旋行波管的高频结构。This paper computed the dispersion characteristic and group velocity of the helically grooved waveguide, simulated the dispersion characteristic of the helically grooved waveguide by methods of ＂quasi-periodic boundary conditions＂ and resonance method, and the results both are good agreement with the computation. Then, the match characteristics of the connection between the tapered and regular helically grooved waveguide, and the transmission characteristics of high frequency system with the helically grooved waveguide were also simulated. The results show that the helically grooved waveguide is a most favorable interaction structure for gyro-TWT.
