摘要
基于耦合波理论,运用阻抗微扰法得到了内开槽螺纹波导的色散方程及耦合条件,并从相对论电子运动方程入手得到了自洽非线性方程组,通过一阶线性近似导出了注-波互作用线性关系及色散方程.运用数值计算及3维粒子模拟软件冷腔分析对该波导冷腔色散特性及注-波互作用色散特性进行了研究.
Based on the theory of coupled-wave, the dispersion equation and coupling condition of helically corrugated waveguide are obtained by the method of impedance perturbation. Then the nonlinear coupled equations are obtained from the relativistic equation which describes the motion of electrons. The numerical calculation and analysis of cold cavity by PIC software are applied to analyze both hot and cold dispersion characteristics of this waveguide.
