Analysis of photonic-crystal problems with MLFMA and approximate Schur preconditioners
We consider fast and accurate solutions of electromagnetics problems involving three-dimensional photonic crystals (PhCs). Problems are formulated with the combined tangential formulation (CTF) and the electric and magnetic ...
Approximate Schur preconditioners for efficient solutions of dielectric problems formulated with surface integral equations
We propose direct and iterative versions of approximate Schur preconditioners to increase robustness and efficiency of iterative solutions of dielectric problems formulated with surface integral equations. The performance ...
