Applicability of the discrete-dipole approximation to high-power laser scattering simulations of haze particles

Optical properties of the fog haze of ammonium sulphate particles including sphere, ellipsoid and cluster consisting of 10 spheres are calculated by using Discrete dipole approximation method (DDA); The change of the efficiency factor with these particles of size parameters and the variation of the ratio of scattering field intensity and the incident field intensity with the scattering angle are obtained and analyzed. The calculation these parameters laid a solid foundation for the following processing of the scattering characteristics of complex particles and the light transmission in the medium of fog haze.
