摘要

本文给出圆突－矩形波导中主模场分量一种近似构造结果的具体表达式，以及用边界元素法解得的截止波长和变分法确定场表达式中待定幂函数的指数常数的具体数值．在假定波导中仅传输主模场的条件下，利用等效原理导出了圆突－矩形波导曲面上纵向缝隙的谐振电导公式，并给出了实际例子，计算和实测获得较满意的结果．

Abstract

The concrete expression of an approximate construction of the field comPOnentsfor the dominant mode in a earn-rectangular waveguide

the cut-off wavelength calculated by usingBoundary Element Method and the concrete functions to determine the uncertain exponent constant of the power function in field expression confirmed by using Variational Method are given atfirst. Assuming only dominant mode propagated

the formula of the resonant conductance for longitudinal slot cut in the curved face of the earn-rectangular waveguide is derived by using the equivalence principlelan actual example is presented and the result of calculation and measurement isquite satisfactory.
