Title   The particle scattering phase function calculation under
different medium environment
Abstract
The radiation characteristics of the particle containing medium are obviously different from the radiation characteristics of the medium, and the particles have the absorption, emission and scattering characteristics of the light, and the influence of the radiation transmission is very complicated.. When the particle size to wavelength ratio to a certain degree, there will be a significant scattering characteristics, this time through the particles of light scattering properties and particle particle size, scattering characteristics are closely related. The scattering phase function describes the distribution of the scattering intensity in the phase and is the important parameter of the particle radiation.. This paper introduces the commonly used research methods of light scattering characteristics of particles, describes the characteristic parameters of the radiation characteristics of particles, and in some necessary assumptions based on Mie theory to calculate the different medium particle scattering phase function, the effects of different media on the direction of the scattering intensity.
