✦ Synopsis

A novel hybrid finite-element method (FEM) and highfrequency 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.

A domain decomposition method (DDM) is presented for the solution of the timeharmonic electromagnetic scattering problem by inhomogeneous 3-D objects. The computational domain is partitioned into concentric subdomains on the interfaces of which Robin-type transmission conditions are prescribed. On t
