Abstract :
A novel hybrid finite element method (FEM) and high frequency technique for the efficient analysis of scattering problems is presented. The hybrid method proposed makes use of an iterative FEM for open region problems that allows the easy hybridization with other numerical techniques. Results of the analysis of 2D scattering problems using physical optics (PO) as the high frequency technique are given showing some of the features of the method.
