“…However, the UV method must pre-determine the rank map of submatrices, which deficient in precisely restoring the original impedance matrix. For moderate problems of finite FSS, the subentire-domain basis function is utilised to simplify the conventional MoM problem into two smaller problems [7] which can be solved more efficiently. However, this method has limitations in analysing multi-screen FSS with different periods.…”

In this study, an efficient numerical technique for transmission characteristic analysis of finite planar frequency selective surface (FSS) with multilayered media is presented by using the multilevel adaptive cross approximation (MLACA). The computational scheme is based on the mixed‐potential electric field integral equation (MPIE) with multilayered media Green's functions (MLGFs). The three‐level modified discrete complex images method (DCIM) is presented for the spatial‐domain MLGFs without any quasi‐static and surface‐wave extraction. For electrically large‐size FSS structures, the MLACA method is then employed to alleviate the high computational complexity and memory requirement of method of moments. Numerical results are presented to demonstrate the accuracy and efficiency of the proposed method.
