A hybrid finite element method (FEM) and high frequency technique (HFT) for the efficient analysis of the radiation and scattering of electromagnetic waves on complex environments is presented. It makes use of FEM for the regions with small and complex features and a HFT for the analysis of the electrically large objects of the structure, taking into account mutual interactions between the FEM domains and the objects analyzed with HF techniques. Results of the analysis of two-dimensional scattering and radiation problems using Physical Optics as the high frequency technique are given showing the main features of the method.
