Computational analysis of complicated metamaterial structures using MLFMA and nested preconditioners
(IEEE, 2007-11)
We consider accurate solution of scattering problems involving complicated metamaterial (MM) structures consisting of thin wires and split-ring resonators. The scattering problems are formulated by the electric-field ...
Iterative solution of dielectric waveguide problems via schur complement preconditioners
(IEEE, 2010-07)
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 ...
The solution of large EFIE problems via preconditioned multilevel fast multipole algorithm
(Institution of Engineering and Technology, 2007)
We propose an effective preconditioning scheme for the iterative solution of the systems formulated by the electric- field integral equation (EFIE). EFIE is notorious for producing difficult-to-solve systems. Especially, ...
Effective preconditioners for large integral-equation problems
(IET, 2007-11)
We consider effective preconditioning schemes for the iterative solution of integral-equation methods. For parallel implementations, the sparse approximate inverse or the iterative solution of the near-field system enables ...
