Efficient Modeling of Complex Electromagnetic Structures Based on the Novel Algorithm for Spatial Segmentation Using Hexahedral Finite Elements

Abstract

A new algorithm for spatial segmentation using hexahedral finite elements, combined with the algorithm for spatial segmentation using quadrilateral elements, is presented. Problems with combining the algorithms for segmentation by hexahedral and quadrilateral elements in the hybrid FEM-MOM technique are pointed out. An example of analysis of a scatterer at resonant frequency is given.
