Harten's scheme for PEEC method

Abstract

The analysis of realistic EMC problems is time and memory consuming. When using integral methods this results in the solution of very large systems that must be solved very carefully because of their ill conditioning. This paper presents a class of multiresolution representations based on Harten's point value multiresolution framework which is used to improve the spectral properties of matrices arising from the Partial Element Equivalent Circuit (PEEC) method. The proposed representation allows the solution being obtained more efficiently by means of iterative solvers that are needed for very large systems.
