Multi-Mode Analysis and Calculation in Waveguide Duplexer
-
摘要: 該文用多模微波網(wǎng)絡(luò)的方法來分析波導(dǎo)頻率雙工器。先將波導(dǎo)頻率雙工器在結(jié)構(gòu)上分割(分解)為相對簡單的單元部件(單元網(wǎng)絡(luò))群，進(jìn)而逐個(gè)分析每一個(gè)單元部件的電磁場邊值問題以獲得該單元網(wǎng)絡(luò)的多模網(wǎng)絡(luò)散射參數(shù)，最后通過多模網(wǎng)絡(luò)參數(shù)矩陣的級聯(lián)，得到整個(gè)器件，即由所有單元網(wǎng)絡(luò)構(gòu)成的合成網(wǎng)絡(luò)的整體散射參數(shù)。

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. -
