#### 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 ...

#### On the accuracy of MFIE and CFIE in the solution of large electromagnetic scattering problems

(ESA Publications, 2006)

We present the linear-linear (LL) basis functions to improve the accuracy of the magnetic-field integral equation (MFIE) and the combined-field integral equation (CFIE) for three-dimensional electromagnetic scattering ...

#### 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 ...

#### Hierarchical parallelization of the multilevel fast multipole algorithm for the efficient solution of large-scale scattering problems

(IEEE, 2008-07)

We present the details of a hierarchical parallelization strategy, which provides higher efficiency than the previous parallelization approaches for MLFMA. We demonstrate the effectiveness of our algorithm on sphere problems ...

#### Efficient parallelization of the multilevel fast multipole algorithm for the solution of large-scale scattering problems

(IEEE, 2006)

We report our efforts for the solution of large electromagnetics problems accurately and efficiently with the parallel multilevel fast multipole algorithm. We carefully investigate different stages of the parallelization ...

#### Comparisons of FMM implementations employing different formulations and iterative solvers

(IEEE, 2003-06)

The implementation of multi-level fast multipole algorithm (MLFMA) requires the consideration of several parameters. The preferred combination of the parameters given is not trivially obvious and requires a careful ...
