For light frequencies well below the resonance frequency of the scattering particle normal dispersion regime , the amount of scattering is inversely proportional to the fourth power of the wavelength. Rayleigh scattering results from the electric polarizability of the particles.

Gilliland, Christopher D. Freel, W. To employ Mie scattering theory to predict the light-scattering from micrometer-sized particles surrounded by lipid shells, called multilamellar bodies MLBs , reported in human age-related nuclear cataracts.

A model of a radially inhomogeneous multilayer spherical particle with a continuously varying refractive index in the intermediate layers between the shells of the particle and between the particle and the surroundings is proposed. Such a particle scatters light much like a dust particle with a rough and ragged surface of the layers, which is simulated with the help of the discrete dipole approximation method.

For dust particles whose surface shape deviates from the spherical one, the refractive index profile and the behavior of the extinction Q ext x and absorption Q abs x efficiency factors with increasing thickness of the intermediate layers are studied. Properties of such particles in dependence on the number of layers are also studied.

It is revealed that, as the number of shells increases, the order of the relative position of substances ceases to play a role, as is also the case for a multilayer spherical particle without intermediate layers. It is shown that, upon an increase in the number of shells at the same percentages of substances in the intermediate layers, the difference of the values of Q ext x and Q abs x from the corresponding values calculated with the model without intermediate layers decreases.

Rayleigh scattering refers primarily to the elastic scattering of light from atomic and molecular particles whose diameter is less than about one-tenth the wavelength of the incident light. Rayleigh line refers to the unshifted central peak observed in the spectroscopic analysis of scattered light.

Absorption and Scattering of Light by Small Particles Treating absorption and scattering in equal measure, this self-contained, interdisciplinary study examines and illustrates how small particles absorb and scatter light. The authors emphasize that any discussion of the optical behavior of small particles is inseparable from a full understanding of the optical behavior of the parent material-bulk matter. To divorce one concept from the other is to render any study on scattering theory seriously incomplete. Enable full ADS. Citations Similar Papers.
