Abstract: Due to the new property of wave front curvature in the Vectorial Complex Ray Model (VCRM), the later permits to simulate with good precision the scattering of large non-spherical particles. This communication presents an exploration of the model with a statistic algorithm – Statistic Vectorial Complex Ray Model (SVCRM), in which the light wave is presented by photons having the same properties of rays in VCRM and the total scattered intensity is calculated statistically by summation of intensity of all photons arriving in the same box in given direction. An analytical description of scattered intensity without interference on a non-spherical object by a plane wave is investigated. And the orders of rays are considered and their corresponding intensity distributions are numerically simulated. Simulated results of scattered field are presented and compared with scattering patterns obtained experimentally for a pendant water droplet. The skeletons of the numerical and experimental patterns are in good agreement. The scattering mechanism of different order rays is revealed.

 

Keywords: light scattering, non-spherical particles, Statistic Vectorial Complex Ray Model, geometrical optics, optical metrology, pendent drop.
