#### Coupled deconvolution for frequency extrapolation of electromagnetic solutions with matrix pencil method

(IEEE, 2005)

Matrix pencil method (MPM) has been widely used to estimate the parameters of complex-exponential based models. An important application is the extrapolation of the frequency-domain solutions of electromagnetic problems. ...

#### Benchmark Solutions of Large Problems for Evaluating Accuracy and Efficiency of Electromagnetics Solvers

(IEEE, 2011)

We present a set of benchmark problems involving conducting spheres and their solutions using a parallel implementation of the multilevel fast multipole algorithm (MLFMA). Accuracy of the implementation is tested by comparing ...

#### On the choice of basis functions to model surface electric current densities in computational electromagnetics

(Wiley-Blackwell Publishing, Inc., 1999-11)

Basis functions that are used to model surface electric current densities in the electric field integral equations of computational electromagnetics are analyzed with respect to how well they model the charge distribution, ...

#### Solid-angle factor in the magnetic-field integral equation

(John Wiley & Sons, 2005)

The magnetic-field integral equation (MFIE) contains a geometry-dependent solid-angle factor due to the limit value of the magnetic field at the source region. Determination of the solid-angle factor becomes bewildering, ...

#### Analysis of photonic-crystal problems with MLFMA and approximate Schur preconditioners

(IEEE, 2009-07)

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 ...

#### 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 ...

#### Efficient surface integral equation methods for the analysis of complex metamaterial structures

(IEEE, 2009)

Two approaches, the multilevel fast multipole algorithm with sparse approximate inverse preconditioner and the surface equivalence principle algorithm, are applied to analyze complex three-dimensional metamaterial structures. ...

#### On the frequency-band selection for ground-penetrating radars operating over lossy and heterogeneous grounds

(IEEE, 2001-07)

The frequency-band selection for ground penetrating radars operating over lossy and heterogenous grounds was discussed. The simulations were carried out using perfectly matched layer (PML) absorbing boundary conditions ...

#### Combined-field solution of composite geometries involving open and closed conducting surfaces

(IEEE, 2005-04)

Combined-field integral equation (CFIE) is modified and generalized to formulate the electromagnetic problems of composite geometries involving both open and closed conducting surfaces. These problems are customarily ...

#### Preconditioning large integral-equation problems involving complex targets

(IEEE, 2008-07)

When the target problem is small in terms of the wavelength, simple preconditioners, such as BDP, may sufficiently accelerate the convergence. On the other hand, for large-scale problems, the matrix equations become much ...
