Abstract

A novel hybrid finite-element method (FEM) and high-frequency technique (HFT) for the efficient analysis of scattering and radiation problems is presented. The proposed hybrid method makes use of an iterative FEM for open-region problems that allows easy hybridization with other numerical techniques. The results of its application to 3D radiation problems using physical optics (PO) and the physical theory of diffraction (PTD) as the high-frequency technique are shown.
