摘要

本文利用阻抗微扰的概念

得到了因截面小变形而引起的各种波型之间的耦合系数。对波导接头问题的分析作了补弃;并由此确定了H

波在接头处所产生的各寄生波幅度。最后按波导椭圆变形的统计特性计算了极化去耦度的期望值。

Abstract

In this paper

formulas for computing the coupling coefficients between waveguide modes caused by wall deformations are obtained by means of the concept of impedance-perturbation. As a supplement to a previous note[5]

waveguide joint problem is then analyzed. From these results the amplitudes of the unwanted modes by a nonideal waveguide joint are derived in case the incident wave is an H11-mode

and the expected value of the de-coupling coefficient between cross-polarized H11-modes is calculated in terms of the statistics of the waveguide elliptical deformation.
