波導(dǎo)E面分支定向耦合器的改進模匹配和網(wǎng)絡(luò)分析
IMPROVED MODE-MATCHING AND NETWORK ANALYSIS OF E-PLANE WAVEGUIDE BRANCH DIRECTIONAL COUPLERS
-
摘要: 本文用多模網(wǎng)絡(luò)理論與嚴(yán)格場匹配相結(jié)合的方法,對波導(dǎo)E面分支定向耦合器作了分析。在分析過程中將電磁場分量用各次LSE~x模疊加來展開,而不是用TE模和TM模來展開。同時通過模匹配將場的問題轉(zhuǎn)化成網(wǎng)絡(luò)的問題來處理。這樣本文方法在不影響計算精度的情況下,具有運算量小,清晰簡捷的優(yōu)點。

Abstract: The E-plane waveguide branch directional couplers are analysed by a method which combines the multi-mode network theory with rigorious mode matching approach. The electromagnetic field components are expanded by the superposition of LSEx modes rather than TE and TM modes in the mode matching procedure. Meanwhile, the electromagnetic problem is transferred into the network problem through the mode matching treatment. It is shown that the present method has the advantages of simplicity and less computation with unaffecting the accuracy of the calculation. -
