A Network Model Decomposition Method Based on Polygon Discretization——Waveguide Eigenvalue Problems

本文将多边形离散技术引入网络模型分解法中,用来求解波导特征值问题。首先通过区域离散化,建立了波导特征值问题的拓扑模型,然后利用场方程的微分形式建立了相应的网络模型。文中最后给出了若干计算实例,验证了该方法的可行性和有效性。

This paper introduces a polygon discretization technique into the network model decomposition method to solve waveguide eigenvalue problems. Through discretizing the waveguide cross section, the topological models of waveguide eigenvalue problems are first established and then the corresponding network models are derived by using the differential forms of the field equations. Finally several numerical examples as a demonstration of the validity and effectiveness of the method are presented.
