#### Accurate solutions of scattering problems involving low-contrast dielectric objects with surface integral equations

(Institution of Engineering and Technology, 2007)

We present the stabilization of the surface integral equations for accurate solutions of scattering problems involving low-contrast dielectric objects. Unlike volume formulations, conventional surface formulations fail to ...

#### 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, ...

#### Solutions of large integral-equation problems with preconditioned MLFMA

(IEEE, 2007)

We report the solution of the largest integral-equation problems in computational electromagnetics. We consider matrix equations obtained from the discretization of the integral-equation formulations that are solved ...

#### Incomplete LU preconditioning with the multilevel fast multipole algorithm for electromagnetic scattering

(Society for Industrial and Applied Mathematics, 2007)

Iterative solution of large-scale scattering problems in computational electromagnetics with the multilevel fast multipole algorithm (MLFMA) requires strong preconditioners, especially for the electric-field integral ...

#### Parallel-MLFMA solution of CFIE discretized with tens of millions of unknowns

(Institution of Engineering and Technology, 2007)

We consider the solution of large scattering problems in electromagnetics involving three-dimensional arbitrary geometries with closed surfaces. The problems are formulated accurately with the combined-field integral ...
