Analysis of Arbitrarily-Shaped Coupling Windows in a Rectangular Waveguide Using the Method of Moments

本文针对任意形状矩形波导耦合窗进行了矩量法分析，给出了它们的散射参量和等效电路参量计算方法。在分析中，未对窗孔的几何形状加任何限制，所得计算公式及计算机软件适宜于分析矩形波导内各类感性耦合窗、容性耦合窗、谐振窗以及其他开有任意形状窗孔的波导膜片。用本文理论方法分析计算了若干波导耦合窗实例，获得了满意的结果。

Arbitrarily-shaped coupling windows in a rectangular waveguide are analyzed by using the method of moments and formulation for calculating their scattering parameters and equivalentcircuit parameters is presented in this paper. Since no restriction is made on the shape of coupling windows in the analysis, the theoretical formulation and corresponding computer software obtained are applicable not only for analysis of various inductive or capacitive windows but also for analysis of arbitrarily-shaped windows in a rectangular waveguide as well. A number of waveguide coupling windows are analyzed by using the present method and the satisfactory results are achieved by comparisons with ones given in some published literatures.
