#### Solution of large-scale scattering problems with the multilevel fast multipole algorithm parallelized on distributed-memory architectures

(IEEE, 2007)

We present the solution of large-scale scattering problems involving three-dimensional closed conducting objects with arbitrary shapes. With an efficient parallelization of the multilevel fast multipole algorithm on ...

#### Fast multipole method in layered media: 2-D electromagnetic scattering problems

(IEEE, 1996)

In this study, the Fast Multipole Method (FMM) is extended to layered-media problems. As an example, the solution of the scalar Helmholtz equation for the electromagnetic scattering from a two-dimensional planar array of ...

#### Multilevel PO algorithm for non-uniform triangulations

(ESA Publications, 2006)

Fast physical optics (FPO) algorithm provides a speedup for computing the physical optics (PO) integral over complex bodies for a range of aspect angles and frequencies. In this paper, this algorithm is further developed ...

#### Fast direct (noniterative) solvers for integral-equation formulations of scattering problems

(IEEE, 1998)

A family of direct (noniterative) solvers with reduced computational complexity is proposed for solving problems involving resonant or near-resonant structures. Based on the recursive interaction matrix algorithm, the ...

#### 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 ...

(IEEE, 2009-06)

In this paper, we consider efficient parallelization of the sparse approximate inverse (SAI) preconditioner in the context of the multilevel fast multipole algorithm (MLFMA). Then, we report the use of SAI in the solution ...

#### Validation through comparison: measurement and calculation of the bistatic radar cross section of a stealth target

(Wiley-Blackwell Publishing, Inc., 2003)

Bistatic radar cross section (BRCS) values of a stealth airborne target are predicted by performing both scaled-model measurements and numerical simulations. In order to achieve the solution of large-scale electromagnetic ...

#### An effective preconditioner based on schur complement reduction for integral-equation formulations of dielectric problems

(IEEE, 2009)

The author consider effective preconditioning of recently proposed two integral-equation formulations for dielectrics; the combined tangential formulation (CTF) and the electric and magnetic current combined-field integral ...

#### Investigation of the inaccuracy of the MFIE discretized with the RWG basis functions

(IEEE, 2004-06)

The inaccuracy of the magnetic-field integral equation (MFIE) discretized with the Rao-Wilton-Glisson (RWG) basis functions is discussed. The electric-field integral equation (EFIE) gives accurate results with the usage ...
