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 coupled wave theory, the dispersion and coupling conditions of the internally slotted waveguide were obtained by the impedance perturbation method. The self-consistent nonlinear equations were obtained from the relativistic electron equations of motion. The first-order linear approximation Linear relationship and dispersion equation of the waveguide.The chromatic dispersion characteristics of the cold cavity and the dispersion of the wave-note interaction in the waveguide were studied by numerical calculation and 3D cavity simulation software cold cavity analysis.
