Title :
Compression of the Method of Moments Matrices Using the Non-Uniform Grid Approach
Author_Institution :

Abstract :
A compression algorithm for the method of moments (MoM) matrices stemming from the discretization of the integral equations of computational electromagnetics is presented. The matrix compression uses domain decomposition and the non-uniform grid (NG) approach. The algorithm effectively removes the oversampling of conventional low-order discretization schemes and adaptively filters out the non-interacting degrees of freedom.
