Fully coupled hybrid‐method FEM/high‐frequency technique for the analysis of 3D scattering and radiation problems

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 ap- plication to 3D radiation problems using physical optics (PO) and the physical theory of diffraction (PTD) as the high-frequency tech- nique are shown. © 2005 Wiley Periodicals, Inc.
