Abstract
We present a novel class of Krylov projection methods computed from the Lanczos biconjugate A-Orthonormalization algorithm for the solution of dense complex non-Hermitian linear systems arising from the Method of Moments discretization of electromagnetic scattering problems expressed in an integral formulation. Their competitiveness with other popular Krylov solvers, especially when memory is a concern, is illustrated on a set of model problems representative of realistic radar-cross section calculations. The results presented in this study will contribute to assess the potential of iterative Krylov methods for solving electromagnetic scattering problems from large structures and to enrich the database of this technology.
