A near interaction preconditioner for MLFMA using overlapped localizing modes

Abstract

The overlapped localizing local global solution matrix factorization algorithm has been shown to provide a fast solution method for low frequency electromagnetic problems. This article shows that the method can be used to rapidly invert the near interaction matrix to produce effective preconditioners for high frequency computational electromagnetic simulations. © 2012 Wiley Periodicals, Inc.
