Abstract

In order to analyze the scattering characteristics of suspended particles in water, a detail research about the intensity distribution of scattering light based on T-matrix theory is presented in this paper. Two kinds of suspended particles: alga and sands are taken into consideration and three kinds of non-spheroid shape model: spheroid, finite circular cylinder and generalized Chebyshev are simulated. The relationship between intensity of scattering light and scattering angle, complex refractive index of suspended particle, wavelength of incident light, size, etc. are calculated. Numerical results show that most scattering light mainly focus on the forward direction and there is a decreasing trend with the increase of scattering angle and wavelength. And when the particles size and the wavelength of incident light changes, the scattered light intensity is significantly changed accordingly for all shape models.
