    Mechanism of Mode Coupling for Gyro-TWT with Helical Interaction Waveguide

      摘要
    • 摘要: 从波导的等效边界条件出发，结合波导的激发方程组，通过数学推导说明了螺旋波纹波导回旋行波管的模式耦合机制。TE1,1模会在螺旋波纹波导中耦合出TE-2,1模，并且通过计算说明TE-2,1模主要和TE1,1模的空间-1次谐波发生耦合。

       

      Abstract: Mechanism of mode coupling for Gyro-TWT with helical interaction waveguide is interpreted in this article, which derived from equivalent boundary conditions and exciting equation. TE1,1 will excited TE-2,1 in helical interaction waveguide.Furthermore, TE-2,1 is primarily coupled with -1 harmonic of TE1,1.
