Efficient Nyström Solutions of Electromagnetic Scattering by Composite Objects With Inhomogeneous Anisotropic Media
2013 Edition, Volume 61, October 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Analysis of electromagnetic (EM) scattering by composite objects with inhomogeneous or anisotropic media requires an efficient solution of volume integral equations (VIEs) or volume-surface integral equations...

Efficient Nyström solutions for electromagnetic scattering by thin conducting structures
2013 Edition, July 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In the integral equation method for solving electromagnetic problems with thin conducting structures, there are several unfavorable factors. The individual electric field integral equation (EFIE) and magnetic field integral equation (MFIE) may deteriorate the conditioning of...

Decoupled potential integral equations for electromagnetic scattering
2018 Edition, March 1, 2018 - Applied Computational Electromagnetics Society (ACES)

In this paper, an integral equation formulation will be presented in terms of decoupled scalar and vector potentials to model electromagnetic scattering from dielectric objects. The formulation can lead to several sets of integral equations with different...

Nyström solutions of electromagnetic scattering by inhomogeneous anisotropic objects
2012 Edition, July 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Analysis for electromagnetic (EM) scattering by inhomogeneous or anisotropic objects relies on the solutions of volume integral equations (VIEs) in the integral equation approach. The VIEs are usually solved by the method of...

Electromagnetic scattering full-wave solver for snowpacks
2017 Edition, July 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The numerical solution of the electromagnetic scattering from a thin layer of snow as a building block for a statistical solver is the major focus of this paper. Both Finite Element Method (FEM) and the Method of Moments (MoM) are used to calculate...

Prediction of electromagnetic scattering from metasurfaces

Starting from reflectarray principles, we derive a formulation to readily predict the electromagnetic scattering of a metasurface when illuminated by an incident plane wave. Examples are shown to illustrate the range of validity and accuracy of the...

Calculation of Electromagnetic Scattering from an Inhomogeneous Sphere
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a finite-element method (FEM), based on a new set of vector basis functions, for an efficient solution of the electromagnetic scattering problem from a continuously varying inhomogeneous sphere. The new bases lead to a large...

Decoupled Potential Integral Equations for Electromagnetic Scattering from Dielectric Objects
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Recent work on developing novel integral equation formulations has involved using potentials as opposed to fields as unknown variables. This is a consequence of additional flexibility offered by potentials that enable development of wellconditioned systems. Until recently, most...

Electromagnetic Scattering From Vegetation Cylindrical Components
2015 Edition, Volume 12, April 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

An approach for calculating electromagnetic scattering, valid in the near- and far-field regions, from a homogeneous finite cylindrical vegetation sample at oblique incidence is presented and discussed. The proposed solution will help in taking into account multiple...

Electromagnetic Scattering Resonances of Quasi-1D Nanoribbons
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We analyse the resonance conditions of a long and narrow ribbon of finite length whether it is conductive or dielectric. This is accomplished by using a full wave approach based on the material independent modes that naturally discriminates the role of the geometry and...
