Simulation of Light Scattering from Spherical Particles in a Volume Element
نویسنده
چکیده
A Monte Carlo method developed in ANSI Standard C-language is presented to simulate polarized light scattering by spherical particles having modal radius of 180nm. Single scattering is considered in this simulation program with monodispersed sub-micron sized spherical CdS particles. The simulation results were compared with experimental results obtained by using Mie-theory. The closeness of agreement or disagreement between these results is discussed in this paper.
