The Combination of Generalized Single-Source TEPA and Contact-Region Modeling for Solving Array Structures

摘要

In this paper, the generalized single-source tangential equivalence principle algorithm (GSST-EPA) is combined with contact-region modeling (CRM) to solve the electromagnetic scattering of array structures. The CRM is used to decompose the array structures into subdomains with the same size. Then each subdomain is enclosed by the same equivalence surface. The GSST-EPA can be used to transfer the unknowns of subdomains onto the equivalence surfaces, which can reduce the number of unknowns and improve the conditioning of final matrix. The numerical results are given to demonstrate the accuracy and efficiency of the proposed method.
