Preconditioned Krylov subspace methods for solving high-frequency cavity problems in electromagnetics

The numerical solution of Maxwell's equations in large unbounded domains may be carried out using the boundary element method, which reformulates Maxwell's equations as a set of integral equations defined on the surface of the scattering object. Method of Moments discretizations of boundary integral equations lead to very large dense linear systems. Fast iterative methods and robust preconditioning are mandatory to use for the solution.
