Ramsauer approach to Mie scattering of light on spherical particles
Abstract. The scattering of an electromagnetic plane wave by a spherical particle was solved analytically by Gustav Mie in 1908. The Mie solution is expressed as a series with many terms thus obscuring the physical insight. The purpose of this paper is to show that when light scattering is described through the Ramsauer model, the physics gets simpler. For instance, the origin of the structures...
متن کاملReduced light-scattering properties for mixtures of spherical particles: a simple approximation derived from Mie calculations.
The reduced scattering cross section per unit of volume Sigma'(s) identical withSigma(s)(1 - g) is an important parameter to describe light propagation in media with scattering and absorption. Mie calculations of the asymmetry factor g for nonabsorbing spheres and Q(sca), the ratio of the scattering cross section Sigma(s) and the particle cross section, show that Q(sca)(1 - g) = 3.28x(0.37)(m -...
متن کاملPredicted light scattering from particles observed in human age-related nuclear cataracts using mie scattering theory.
PURPOSE 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. METHODS Mie scattering theory is applicable to randomly distributed spherical and globular particles separated by distances much greater than the wavelength of incident light. Wi...
متن کاملMie theory for light scattering by a spherical particle in an absorbing medium.
Analytic equations are developed for the single-scattering properties of a spherical particle embedded in an absorbing medium, which include absorption, scattering, extinction efficiencies, the scattering phase function, and the asymmetry factor. We derive absorption and scattering efficiencies by using the near field at the surface of the particle, which avoids difficulty in obtaining the exti...
متن کاملLight Scattering by Marine Particles: Modeling with Non-spherical Shapes
The inherent optical properties (IOPs) of marine particles are most-often modeled and interpreted by assuming that they are homogeneous spheres. Although this approach has been fruitful, the next logical step in modeling the IOPs of marine particles is to abandon the normally-employed spherical approximation and use more realistic idealizations of their shape. The advent of computer codes capab...
