Analysis of evanescent waves conversion by a non-spherical particle near a metal-coated glass prism via discrete sources method

摘要

The discrete sources method is extended to analyse evanescent waves scattering by a non-spherical particle located near a metal-coated glass prism. A metallic film is designed to enhance conversion of an evanescent wave into a scattered one via computational simulations. The importance of taking into account interaction between scatterer and multi-layered interface is demonstrated.
