Abstract

The analytical approaches based on the modified Wentzel-Krammers-Brillouin (WKB) and equiphase-sphere (EPS) methods that enabled accurate characterization of light scattering with irregularly shaped dielectric particles was discussed. It was observed that the approach had the potential to address the inverse-scattering problem by probing the sizes and geometric characteristics of arbitrarily-shaped particles. Gaussian random spheres were also used as test models to evaluate the validity and accuracy of both approximate methods. The modified WKB and EPS approximation acted as valuable tools for the analysis of light scattering from irregular particles in many applications.
