摘要：The paper understudy develop an extended version of the method of auxiliary sources EMAS in the purpose of modeling the scattering response by finite arrays constituted by conducting or dielectric infinite cylinders. The suitable boundary conditions assorted with the judicious decomposed domains guide to the computation of the backscattering cross section. The global electromagnetic coupling between the cylinders is also integrated in the algorithm. The coupling modeled by the mutual satisfaction of the boundary conditions involves the continuity of the total tangential field components and focuses on the collocation points of every cylinder. The partial coupling model implements the coupling only between neighboring cylinders. Thus, the linear system matrix is fully simplified, entraining a significant decrease in the computational cost and memory requirements. According to the global and partial coupling, the numerical results (RCS, pattern field) reveal satisfying agreement with references.
