A two-level ILU preconditioner for electromagnetic applications

In this work we consider the solution of the linear systems arising from electromagentism applications by preconditioned Krylov subspace methods [3]. Simulation of electromagnetic wave propagation phenomena requires the numerical solution of Maxwell’s equations which it is often done by means of integral equation methods. The discretization of the integral equations with the boundary element method results in dense linear systems of the form, Ax = b (1)
