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 ...
Iterative solution of dielectric waveguide problems via schur complement preconditioners
Surface integral-equation methods accelerated with the multilevel fast multipole algorithm provide suitable mechanisms for the solution of dielectric problems. In particular, recently developed formulations increase the ...
