Abstract

In this paper we present the analysis at very low frequencies of topologically complex structures through the Electric Field Integral Equation (EFIE), discretized by the Method of Moments (MoM). The linear system is stabilized at very low frequencies via the Multi-Resolution preconditioner, where an Helmholtz decomposition of the unknown current is automatically performed to multiple connected objects. Numerical results show the fast and stable convergence of the applied iterative solver.
