Abstract:
An efficient approach to simulate the multiple scales, occurring in metascreens, is introduced. Due to the fine discretization around apertures, the standard finite element (FE) method leads to a large number of unknowns. Therefore, the generalized FE method is applied with multiscale functions, which are supported locally at the apertures. The idea is to develop a technique that is able to cope with varying thicknesses of the metascreen and arbitrary shapes of apertures as well as lossy materials and frequencies in a wide range. The proposed method improves the accuracy in simulations for metascreens in 2-D.
