摘要

This paper presents the application of the generalized boundary integral-resonant mode expansion (BI-RME) method to the analysis of dielectric-loaded waveguide filters. The method is based on the segmentation/recombination technique, which permits to divide the component into homogeneously-filled building blocks. The BI-RME method is used to calculate the generalized admittance matrix (GAM) of each arbitrarily shaped building block by solving an integral equation, which is obtained enforcing the appropriate boundary condition to the electromagnetic field. The GAMs are then cascaded to obtain the frequency response of the whole component. Any possible shape of the interconnecting surfaces can be treated with this implementation due to the adoption of the RWG basis functions to represent the unknown electric and magnetic surface currents. The theory of the method is outlined in this paper, and a numerical example demonstrates the capabilities of the proposed algorithm.
