Analysis of the light scattering properties of a gold nanorod on a plane surface via discrete sources method

The Discrete Sources Method has been extended to analyze the scattering behavior of a gold nanorod deposited on a plane surface in an evanescent wave field. In this case the system particle-surface demonstrates no axial symmetry and it is not possible to apply the conventional DSM approach for axisymmetric systems used before. In this paper DSM algorithm for non-axisymmetric systems is presented. The rigorous computer model based on DSM, which allows to take into account all features of the scattering problem including particle-surface interaction has been realized. Computer simulation analysis of the scattering spectra of gold nanorod is presented.
