## Abstract A high‐order vector finite‐element method (FEM) is presented for the analysis of 3D frequency‐selective structures (FSSs). The asymptotic waveform evaluation (AWE) technique is combined with the FEM to perform fast frequency and angular sweeps. Reflection/transmission characteristics of
