Using MGAWE Method for Waveguide Structure Analysis Based on Finite Element DDM

The broadband electromagnetic response of complex waveguide structure using domain decomposition method (DDM) still remains a formidable challenge. To address the efficient computation of the electromagnetic responses over a wide frequency band, multipoint Galerkin asymptotic waveform evaluation (MGAWE) based on DDM has been adopted in this paper. The resulting solution procedure of using MGAWE to solve complex waveguide allows for wideband frequency simulations with a reduction in total computation time. Numerical simulations using these methods are shown along with discrete sweep frequency calculated by HFSS software at each frequency point of interest.
