A hybrid scheme of the discrete sources method for analyzing boundary value problems of nano-optics

Abstract

The problem of the diffraction of a plane linearly polarized wave on a nanodimensional elongated particle located on a permeable substrate is considered. A hybrid scheme of the discrete sources method with allowance for particle geometry is used to construct the solution. The proposed scheme is substantiated mathematically with certain constraints on particle thickness. Numerical results illustrating the capabilities of the method are presented.
