Modeling of scattering intensity of spheroid particles with a Gaussian beam

Abstract

Based on the Generalized Lorenz Mie Theory (GLMT), the scattering intensity of spheroid particles is investigated within the Gaussian beam. The spheroid model is applied to represent the real non-spherical particles, and the scattering intensity of particles is deduced according to the GLMT. On the other hand, the sphere of the same volume for the spheroid is used for calculating the scattering intensity of the spheroid within the Gaussian beam. For a comparison, the scattering intensity of the spheroid with the pane wave is also calculated. Simulation data results indicate that fairly reasonable results of the scattering intensity for the spheroids can be obtained with this model, and it can provide a reliable and efficient approach to research the scattering intensity of the non-spherical particles by the Gaussian beam.
