Software framework for integration of method of moments kernels with the Adaptive Cross Approximation (ACA) algorithm

This paper presents a software framework that allows the integration of efficient fast iterative and direct solvers with various Method of moment (MoM) engines. The idea leads to a future open-source software project to integrate modules developed by different University groups with expertise either in accurate computation of Integral Equations Green´s functions or in developing Fast Solvers for efficient solution of the resulting linear systems. The integrated software will allow the successful analysis of very complex antenna configurations that cannot be handled yet by commercial packages.
