【 摘 要 】

References(10)It is well known that the rate of convergence of the Krylov Subspace Methods (KSMs) applied to the solution of the linear systems of equations arising from the discretization process of the E-Field Integral Equation (EFIE) by Method of Moments (MoM), can be improved by a suitable preconditioning strategy. In this paper, we analyze the performances of an easy preconditioner based on the skew-Hermitian part X of the impedance matrix Z. Numerical examples illustrate its performances and validate the proposed approach.
