Scattering and polarization properties of a complex refractive index spherical particle

The scattering intensity and polarization properties of different size particles are simulated by the Ricatti-Bessel functions.As the size of particles increases,the scattering intensity increases;as the size of particles increases,the horizontal polarization becomes unsymmetrical while vertical polarization invariable;with the imaginary parts of complex refractive index increasing,the scattering intensity decreases.From these properties,various kinds of particles can be measured and taken apart.
