Transform Approach to Electromagnetic Scattering

Proceedings of the IEEE, 1979
In this paper, we present a comprehensive review of the Fourier transform technique as applied to the problem of high-frequency scattering and introduce the concepts of the spectral theory of diffraction (STD). In contrast to the more commonly employed ray-optical method for high-frequency scattering, viz.

Electromagnetic scattering by buried cylinders

2007 4th International Workshop on, Advanced Ground Penetrating Radar, 2007
A spectral-domain method, for the solution of the two-dimensional electromagnetic plane-wave scattering by a finite set of perfectly conducting or dielectric cylinders buried in a dielectric half-space, has been developed. The scattered field is represented in terms of a superposition of cylindrical waves, and use is made of the plane-wave spectrum to ...

Electromagnetic Modeling of Scattered GNSS Signals

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
The quasi-specular reflection collected under the illumination of signals of opportunity can exhibit temporal fluctuations related to the characteristics of the surface roughness. Even in quite flat regions, gentle undulations, i.e., those comparable with the wavelength over the vertical scale and much longer over the horizontal one, can exist and can ...

Electromagnetic Scattering by an Inhomogeneous Impedance Cylinder

AEU - International Journal of Electronics and Communications, 2002
Summary In this paper, the electromagnetic scattering problem related to a circular cylinder with inhomogeneous impedance boundary is solved. This kind of problem may have practical applications such as antenna design since one can obtain a certain radiation pattern by choosing thesurface impedance in an appropriate way.

Domain Derivatives in Electromagnetic Scattering

Mathematical Methods in the Applied Sciences, 1996
The author studies the differentiable dependence of a class of boundary operators on the region of integration. He extends his results to the case of operators which occur in the treatment of time harmonic electromagnetic scattering problems by boundary integral equation methods.

Electromagnetic Scattering by Periodic Structures

Journal of Mathematical Sciences, 2004
The paper considers the existence and uniqueness problem for the stationary scattering of electromagnetic waves (diffraction) on a structure which is localized in the propagation direction of the wave, and is periodic in two other directions, taking piece-wise constant values (this corresponds to the usual structure of diffraction gratings).

Broadband electromagnetic scattering by particles

Journal of the Optical Society of America A, 2008
The so-called sum rule for the extinction cross section has been the subject of several publications. However, it has not been obtained directly from the macroscopic Maxwell equations but rather follows from heuristic causality considerations. It is argued that these causality considerations are, in fact, questionable and do not follow from the ...

Scattering of electromagnetic radiation

2023
Abstract In this chapter we discuss the scattering of electromagnetic waves by charged particles. We define the scattering cross-section. We then consider the scattering of electromagnetic waves from free electrons, giving rise to the Thomson cross section, expressed in terms of the classical electron radius.

Electromagnetic scattering of hyperons

Il Nuovo Cimento, 1961
The interaction between the magnetic moment of a neutral hyperon and the charge of a nucleus causes large polarizations in small-angle scattering. The feasibility of using the effect to measure the magnetic moment is considered.
