摘　　要：本文介绍由长缝隙耦合的端头对接的波导接头的电特性。利用伽略金法求解缝隙口面上等效磁流,获得散射场及其等效参量的通用表达式。波导尺寸,缝隙尺寸和位置是任意的。给出了数值计算实例和实验数据,二者相吻合。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 calculaion and experiments are given. The theoretical and experimental results are in good agreement.
