FEM-DDM-BEM for a 3-D Electromagnetic Scattering Analysis of Metal Dieletric Composite Structure

Abstract

This paper presented an effective preconditioning technique for iteratively solving FE-BI equation. In this method, the first order Robin-type TC is used to connect the interfaces of FEM and BI regions and the second order TC is used to joint the interfaces in interior FEM regions. The method not only provides a robust and effective preconditioner but also gives a novel way to establish and deal with eletromagnetic models.
