There are two major difficulties in applying the finite element method to the analysis of microwave devices in three dimensions. One is to obtain a stable vector finite element which does not generate spurious modes, or non-physical solutions, in the numerical analysis. The other is to model efficie
## Abstract A highβorder vector finiteβelement method (FEM) is presented for the analysis of 3D frequencyβselective structures (FSSs). The asymptotic waveform evaluation (AWE) technique is combined with the FEM to perform fast frequency and angular sweeps. Reflection/transmission characteristics of
