摘要
本文利用微分形式理论,建立了波导特征值问题的拓扑模型及其相应的网络模型,然后利用网络分解节点分析法,建立了计算任意截面金属波导截止波数的一般算法。最后将该算法应用于几个典型波导,验证了该算法的可行性和有效性。
The toplogical model and the corresponding network model are established for waveguide eigenvalue problems by using the theory of differential forms in this paper. A general algorithm for evaluating the cut-off wavenumbers of an arbitrarily shaped waveguide is constructed through diakoptic node analysis. Finally the algorithm is applied to several typical waveguides, demonstrating the validity and effectiveness of the method.
