摘要
给出了更严密的脊波导本征函数的表达式,并运用驻波法推导了完整的脊波导的特征方程。采用模匹配法推导矩形-脊波导不连续性的广义S矩阵,将其进行了计算机编程,最终得到与HFSS仿真一致的结果。
The more rigorous expression of ridged waveguide eigenfunction is presented. Standing wave formulation is used to derive the complete characteristic equations of ridged waveguide. The mode-matching technique is employed for computing the generalized scattering matrix of discontinuity of the rectangular-ridged waveguide. The algorithm is translated into PC-operation software. Results are compared with HFSS, and are found to be in good agreement.
