Abstract
In this paper, the Multiresolution (MR) approach is here used to generate an efficient, physics-based preconditioning scheme, particularly suitable for fast Method-of-Moments (MoM) methods as FMM and AIM, that present low computational complexity. In fact, unlike other preconditioners, it requires a low memory occupation and computational cost for its generation and application. Its application reduces the overall computational cost of the fast method of more than one order of magnitude, and results in a total gain with respect to the standard MoM of almost three orders of magnitude.
