Approximate solutions for radii very small compared to wavelength are derived, the wavelengths for which the effects of multiple scattering are greatest are investigated, and a criterion for the use of the single scattering hypothesis presented. Solutions for two bosses and a single cylinder parallel to a nonabsorbing plane are also stated.
In addition to multiple scattering, the radiation is scattered predom-inantly into the forward direction for the case of radiation incident upon relatively large particles. These conditions of multiple scattering and a highly anisotropic scattering pattern occur frequently in hazes, fogs, clouds, smoke, and dust.
Definition multiple scattering is an effect due to propagation of waves through a medium characterized by a random distribution of discrete scatterers, usually embedded in a continuum medium.
We present the first numerical radiative transfer simulation of multiple light scattering in dust configurations containing aligned non-spherical (spheroidal) dust grains. Such models are especially important if one wants to explain the circular polarization of light, observed in a variety of astronomical objects. The optical properties of the spheroidal grains are calculated using the method.
The rayleigh scattering model breaks down when the particle size becomes larger than approximately 10% of the wavelength of the incident radiation at which point mie theory must be applied. The mie solution is obtained through an analytical solution of maxwell’s equations for the scattering of electromagnetic radiation by spherical particles.
A formal solution in terms of cylindrical wave functions is obtained for the scattering of a plane acoustic or electromagnetic wave by an arbitrary configuration of parallel cylinders which takes into account all possible contributions to the excitation of a particular cylinder by the radiation scattered by the remaining cylinders.
The formal solution for the scattering of a plane wave by an arbitrary configuration of parallel cylinders previously presented is specialized to consider the case where all the axes lie in the same plane. The scattered wave is expressed as an infinite sum of orders of scattering, the first order being the usual single scattering approximation.
This property is useful for volume scattering implementations, since it makes it possible to incrementally compute transmittance at multiple points along a ray: transmittance from the origin to a point can be computed by taking the product of transmittance to a previous point.
Scattering is a term used in physics to describe a wide range of physical processes where reflections of radiation that undergo scattering are often called diffuse cases, radiation may scatter many times, in what is known as mult.

Scattering is a term used in physics to describe a wide range of physical processes where moving particles or radiation of some form, such as light or sound, is forced to deviate from a straight trajectory by localized non-uniformities (including particles and radiation) in the medium through which they pass.

Each kernel is multiplied by a factor, f, that weights the relative contribution of surface-scattering ( f geo) and volume-scattering ( f vol) to the measured brdf. The term f iso is included to account for isotropic scattering from the surface (in practice, this includes contributions from both single-scattering and multiple-scattering).
The result of either coherent scattering or the compton effect is termed scatter radiation or simply scatter. Radiation produced by the photoelectric effect is correctly referred to as secondary radiation. Since more than one type of interaction takes place during radiography and the resulting radiation is so similar, the terms are often used.
This paper extends this idea, and uses the equation of energy transfer for radiation in a uniform scattering atmosphere to describe the variation of average intensity.
