Preconditioning Techniques in the Analysis of Finite

Abstract—In the method of moments (MoM) electric field integral equa-tion (EFIE) analysis of slabs of metamaterials, we show that a left-precon-ditioning scheme by blocks gathering interactions between basis functions belonging to each basic cell of the metamaterial reaches convergence in less iterations and with less computational time than a left-preconditioner based on discarding interactions between basis functions beyond a given distance.
