  • Resumen
    • The discretization of the Electric Field Integral Equation (EFIE) leads to the solution of a dense complex non-hermitian linear system. It is well-known that the related linear system becomes ill-conditioned particularly when the frequency increases. As a consequence, its solution by a subspace Krylov iterative algorithm has a very slow convergence. In this work, we examine the possibility to speed up the convergence by constructing a Calderón-type implicit preconditioner.
