Abstract :
This paper has an emphasis on the HF part; we use physical-optics (PO) method [1] with large-dimension curvilinear elements [2]. On the LF side, the hybrid method proposed here employs the FEM domain decomposition method (DDM) [3-4]. In addition, an iterative Multi-Region procedure is developed to make the information between sub-regions fully exchanged.
