Mie scattering by ensembles of particles with very large size parameters

Mie scattering by ensembles of particles with very large size parameters

We present a computer program for the simulation of Mie scattering in case of arbitrarily large size parameters. The elements of the scattering matrix, efficiency factors as well as the corresponding cross sections, the albedo and the scattering asymmetry parameter are calculated. Single particles as well as particle ensembles consisting of several components and particle size distributions can...

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...

Measuring Mie Scattering from Ionized, Trapped Dielectric Particles

Inelastic light scattering by large structured particles.

Autocorrelation functions are computed for nonspherical particles whose dimensions are comparable to or greater than the wavelength of scattered light. Particular attention is given to models of motile microorganisms. Results for Gaussian ellipsoids, finite thin rods, ellipsoids with internal structures, and dumbbell-shaped scatterers are derived and compared.

Scattering of very light charged particles.

I advance arguments against the view that the Lee-Nauenberg-Kinoshita theorem is relevant in practice to the scattering of charged particles as their mass tends to zero. I also discuss the case of massive coloured particle scattering. Scattering cross-sections for reactions involving, in the initial state, a charged particle of mass m contain (in perturbation theory) ln m terms, which become la...
