矩量法的一般波端口电磁建模方法
Electromagnetic modeling of general waveports with the method of moments
摘要
Abstract
For the problems of electromagnetic modeling of waveports with irregular cross-sections by the integral equation method,a general waveport modeling method based on the higher-order method of moments is proposed.We establish the waveport surface integral equations based on the equivalence principle and the mode matching(MM)method.Additionally,we utilize the two-dimensional finite element method(2-D FEM)to accurately analyze the modes of irregular waveports,thereby extending the modeling capability of the MoM from the regular waveport model to a general waveport model suitable for both regular and irregular waveports modeling,on the basis of which the adoption of the higher-order basis functions defined on quadrilateral elements instead of lower-order basis functions reduces the unknown of the MoM,thus significantly reducing the memory requirements and computation time.The proposed method is tested through numerical examples,and the comparison of the tested results with the numerical results of the FEM verifies the correctness of the proposed method,and the comparison with RWG-MoM verifies the efficiency.Numerical results show that the proposed method has the advantages of high efficiency and high numerical accuracy for the general waveport modeling.关键词
