Broadband full-wave frequency domain PEEC solver using effective scaling and preconditioning for SIPI models

Abstract

In this paper, a new iterative full-wave frequency domain PEEC solver is proposed. Based on the classical modified nodal analysis, the convergence of the iterative solution is optimized by resorting to a pertinent scaling of sub-matrices which improves the conditioning of the global left hand side matrix and to a multiscale-based effective preconditioner. The efficiency of the proposed approach in terms of either accuracy and number of iterations is demonstrated through its application to a relevant problem.
