Elastic scattering of evanescent electromagnetic waves

Applied Optics, 1979
Analytic and numerical results are given for the elastic scattering of evanescent electromagnetic waves by dielectric spheres. Some polarization and symmetry effects not found in Lorenz-Mie scattering are noted. The possibility of experimental studies is also discussed.

Multiple-scattering theory for electromagnetic waves

Physical Review B, 1993
In this paper, a multiple-scattering formalism for electromagnetic waves is presented. Its application to the three-dimensional periodic dielectric structures is given in a form similar to the usual Korringa-Kohn-Rostoker form of scalar waves. Using this approach, the band-structure results of touching spheres of diamond structure in a dielectric ...

Spectral Simulations of Electromagnetic Wave Scattering

Journal of Computational Physics, 1997
The authors consider the problem of two-dimensional scattering of electromagnetic waves by circular and elliptic cylinders and the calculation of the associated radar cross section. They allow for fields at infinity by introducing a fictitious absorbing layer at a finite distance from the cylinder. Various methods of calculation (finite-difference-time-

Electromagnetic Wave Dynamics in Matter-Wave Superradiant Scattering

Physical Review Letters, 2010
We present a small-signal wave propagation theory on matter-wave superradiant scattering. We show, in a longitudinally excited condensate, that the backward-propagating, superradiantly generated optical field propagates with ultraslow group velocity and that the small-signal gain profile has a Bragg resonance.

Electromagnetic Wave Scattering From Small Scatterers of Arbitrary Shape

Journal of Electromagnetic Waves and Applications, 2000
Summary: Scattering of electromagnetic waves from arbitrary shaped dielectric particles that are small compared to the wavelength in surrounding medium is studied theoretically by means of the local perturbation method generalized for vector equations.

Scattering theory of stochastic electromagnetic light waves

Optics Letters, 2010
We generalize scattering theory to stochastic electromagnetic light waves. It is shown that when a stochastic electromagnetic light wave is scattered from a medium, the properties of the scattered field can be characterized by a 3 x 3 cross-spectral density matrix.

Scattering of electromagnetic waves by electron acoustic waves

Planetary and Space Science, 1987
It is shown that a large amplitude electromagnetic wave can parametrically excite low-frequency electrostatic modified electron acoustic waves which are unique to three-component plasmas containing ions, hot electrons and a group of cold electrons. The growth rates and thresholds of the decay instabilities are obtained.

Scattering of Electromagnetic Waves by Longitudinal Plasma Waves

The Physics of Fluids, 1960
It is shown that Bragg reflection of electromagnetic waves from plasma oscillations is possible. The wave equation for the electromagnetic field passing through a medium of plasma waves is derived, and it is found to be similar to that of Brillouin for a wave in a medium of variable dielectric constant.

Electromagnetic Wave Scattering from Rough Terrain

1980
Abstract : This report presents two aspects of a program designed to calculate electromagnetic scattering from rough terrain: (1) the use of statistical estimation techniques to determine topographic parameters and (2) the results of a single-roughness-scale scattering calculation based on those parameters, including comparison with experimental data ...
