摘要

波导不连续性区域的场分布用网络模型中的节点电压来表示

而不连续区域外部的场则等效成排列于边界节点上的电流源。利用网络分解节点分析法则可确定任意H面或E面不连续性的[S]参数。文中给出了若干数值结果

验证了该方法的可行性和有效性

Abstract

The field distribution of the waveguide discontinuity region has been represented by the nodal voltage in network model

and the field external to the region has been replaced by equivalent current sources connected to the boundary nodes. The [S] parameters of an E-plane or H-plane discontinuity can be determined by using the diakoptic node analysis in electric circuit theory. Numerical results are also presented as a demonstration of the validity and effectiveness of the method. In present analysis

the power conservatiom condition is satisfied to an accuracy of ±10-5.
