Light scattering by anisotropic particles

Astrophysics and Space Science, 1976
The Stokes parameters of radiation scattered by anisotropic particles (cosmic dust grains or molecules) are calculated. The effective mechanisms of transformation of the linear polarization into the circular one by free-oriented anisotropic particles are proposed.

Anisotropic scattering in photorefractive crystals

Journal of the Optical Society of America B, 1986
A well-defined ring of anisotropically scattered light is observed when a linearly polarized laser beam is incident upon a birefringent photorefractive crystal such as BaTiO3, LiNbO3, and LiTaO3. An analysis is presented that accurately predicts the cone angle, polarization, and the location of the discontinuities in these rings.

Inverse Scattering Problem in Anisotropic Media

Communications in Mathematical Physics, 1998
Second-order elliptic equations in \(\mathbb{R}^n\) which carry no smallness assumptions on the coefficients are considered (and rewritten as an Laplace-Beltrami equation). From the scattering amplitudes the integrals are recovered. So it is possible to obtain a class of scattering invariants (constructed from the amplitude) by using results of ...

Slowing Down with Anisotropic Scattering

Nuclear Science and Engineering, 1962
The technique of expanding Laplace transforms in a series of the transform variable before inversion was applied earlier to determine the flunx obtatned from an energy distrlbuted neutron source in an lnfinlte homogeneous system. This method is extended to slowing down when the dlfferential scattering cross sectlon of the nuclei is anisotroplc ln the ...

Optical logic by anisotropic scattering

Optics Communications, 1985
Abstract An optical logic processor is presented that can handle large data arrays in parallel. The logic operation itself is easy to perform by means of spatial filtering. Not so easy (in real-time) is the encoding of the data before processing. The logic states (zero or one) are represented by anisotropic scattering properties of the transparency ...

SCATTERING FROM A SMALL ANISOTROPIC ELLIPSOID

Canadian Journal of Physics, 1958
Scattering of an electromagnetic wave by a small ellipsoid having tensor permeability and dielectric properties is dealt with by expanding the fields as power series in λ−1. Consideration has been given to the first three terms of the expansion.

Anisotropic multiple scattering of light

Photonic Metamaterials: From Random to Periodic, 2006
We report on the first observation of anisotropy in weak localization of light from ordered nematic liquid crystals and on vectorial Monte Carlo simulations of anisotropic multiple scattering and weak localization using anisotropic Rayleigh scatterers.

Light scattering in anisotropic stratified media

Physical Review E, 1994
We determine exact formulas, in the Born approximation, for the scattering cross sections of the electromagnetic field propagating in a scattering anisotropic stratified medium having an arbitrary variation of the average dielectric tensor along the longitudinal direction and bounded by outermost isotropic homogeneous media.

Rainbow scattering from anisotropic potentials

Journal of Physics C: Solid State Physics, 1977
The leading term in a semiclassical expansion of the quantum mechanical cross section for potential scattering is obtained for those cases where the classical cross section shows either a fold or an umbilic (hyperbolic or elliptic) type catastrophe. As an intermediate step a narrow wave packet approximation is derived by decomposing the S-matrix into ...

Light Scattering by Anisotropic Shells

Journal of Applied Physics, 1970
Solid-state light scattering using a red laser source has been applied to the study of spherulitic shells of polyethylene and gelatin. The Hv scattering patterns from a collection of shells are qualitatively similar to that of a spherulite. However a single shell gives a scattering pattern wherein several orders of maxima within the recordable range ...
