波导频率双工器的多模分析计算
Multi-Mode Analysis and Calculation in Waveguide Duplexer
-
摘要: 该文用多模微波网络的方法来分析波导频率双工器。先将波导频率双工器在结构上分割(分解)为相对简单的单元部件(单元网络)群，进而逐个分析每一个单元部件的电磁场边值问题以获得该单元网络的多模网络散射参数，最后通过多模网络参数矩阵的级联，得到整个器件，即由所有单元网络构成的合成网络的整体散射参数。

Abstract: A H-plane waveguide duplexer is analysized with a multi-mode microwave network method in this paper. This method is carried out through three steps: dividing the microwave device to be analyzed into a group of unit components at first, then numerically solving, the electromagnetic boundary-value problems of components one by one to yield their multi-mode network scattering parameters, finally re-combining all the unit components to obtain the total scattering parameters of the original devices to be analyzed. -
