摘要：

A modeling methodology to obtain the dispersion characteristics of mirror- and glide-symmetric structures is presented. A novel Green's function is proposed as the integration kernel of the electric-field integral equation solved by the method of moments (MoM). Key aspects of implementation, such as adapting the Ewald acceleration, accurate computation of singular integrals, and a zero-search algorithm to obtain solutions, are presented. The proposed methodology is applied to fully metallic 2-D periodic unit cells with arbitrary geometries. The results of the method are found to be in very good agreement with reference results from the literature. Compared to the conventional MoM analysis, the proposed approach obtains results in half the time and gives additional information about the modal properties.
