摘要: 本文介紹由長(zhǎng)縫隙耦合的端頭對(duì)接的波導(dǎo)接頭的電特性。利用伽略金法求解縫隙口面上等效磁流,獲得散射場(chǎng)及其等效參量的通用表達(dá)式。波導(dǎo)尺寸,縫隙尺寸和位置是任意的。給出了數(shù)值計(jì)算實(shí)例和實(shí)驗(yàn)數(shù)據(jù),二者相吻合。

Abstract: The coupling properties of a transverse slot in the common wall between butting two rectangular waveguides are discussed. By means of Galerkin s method which takes into account the wall thickness, equivalent magnetic currents on the aperture surface of the slot are obtained, and then general formulas of scattering fields and of .equivalent parameters arc derived. The dimensions as well as seats of those two waveguides and the slot, and the thickness of the wall are arbitrary. For example, the transforming coefficients and the VSWRs of numerical calculation and experiments are given. The theoretical and experimental results are in good agreement. -
