New scheme of the Discrete Sources Method for light scattering analysis of a particle breaking interface

The Discrete Sources Method (DSM) has been modified to analyze polarized light scattering by an axial symmetri  c penetrable nanoparticle partially embedded into a substrate. The new numerical scheme of the DSM enables to consider scattering from such substrate defects as flat particles, mounds, pits and voids. A detailed description of the numerical scheme is provided. The developed computer model has been employed to investigate scattering from a shallow particle and pit. Simulation results corresponding to the Differential Scattering Cross-Section and the integral response for P/SP/S polarized light are presented.
