Scattering of randomly distributed spherical particles illuminated with a Gaussian beam

Abstract

Based on the generalized Lorenz Mie theory, the light scattering of randomly distributed spherical particles in the Gaussian beam is investigated. Three different sampling regions are defined in order to determine the distribution range of random particles, and then the uniform sampling of multi-particles is conducted, respectively. Moreover, an average method based on the statistical average is proposed to represent the scattered field of multi-spheres. Simulation experiments indicate that fairly reasonable results of the total scattering intensity for the multi-spheres can be obtained with the proposed method, and it provides a simple, reliable and efficient method to reproduce the scattering properties of randomly distributed particles illuminated by the Gaussian beam.

“…For a measured particle system, the particles can be distributed anywhere within the Gaussian beam [18]. Here, we de ne the particles in the semicircular region, that is, Table 1 shows the scattering cross section of the sphere particle with di erent location in the Gaussian beam.…”
