On the Preconditioning of the Algebraic Linear Systems Arising from the Discretization of the EFIE

摘要

The rate of convergence of the Generalized Minimum Residual Method (GMRES) applied to the dense linear systems arising from discretization of EFIE integral equation by Method of Moment (MoM) depends heavily by preconditioning. In this work, we evaluate the performances of a simple preconditioner based on the skew hermitian component S of MoM impedance matrix Z for the case of plane wave scattering by CEP bodies.
