#### 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 ...

#### Electromagnetic imaging of three-dimensional dielectric objects with Newton minimization

(IEEE, 2014)

We present a general framework for detecting the shape and electrical properties of unknown objects by using the Newton minimization approach for solving inverse-scattering problems. This procedure is performed by evolving ...

#### Subsurface-scattering calculations via the 3D FDTD method employing PML ABC for layered media

(IEEE, 1997)

A three-dimensional finite-difference time-domain method that employs pure scattered-field formulation and perfectly matched layers (PML) as the absorbing boundary condition is developed for solving subsurface-scattering. ...

#### 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, ...

(IEEE, 2011)

We present a fast and accurate analysis of double-negative materials (DNMs) with surface integral equations and the multilevel fast multipole algorithm (MLFMA). DNMs are commonly used as simplified models of metamaterials ...

#### PO-MLFMA hybrid technique for the solution of electromagnetic scattering problems involving complex targets

(Institution of Engineering and Technology, 2007)

The multilevel fast multipole algorithm (MLFMA) is a powerful tool for efficient and accurate solutions of electromagnetic scattering problems involving large and complicated structures. On the other hand, it is still ...

#### Optimal interpolation of translation operator in multilevel fast multipole algorithm

(Institute of Electrical and Electronics Engineers, 2006)

Lagrange interpolation of the translation operator in the three-dimensional multilevel fast multipole algorithm (MLFMA) is revisited. Parameters of the interpolation, namely, the number of interpolation points and the ...

#### Hybrid CFIE-EFIE solution of composite geometries with coexisting open and closed surfaces

(IEEE, 2005)

The combined-field integral equation (CFIE) is employed to formulate the electromagnetic scattering and radiation problems of composite geometries with coexisting open and closed conducting surfaces. Conventional formulations ...
