Non-axisymmetric models for light scattering from a particle on or near a plane surface

The communication is devoted to semi-analytical approaches for analyzing the scattering by a non-axisymmetric structure consisting of a nonspherical particle and a plane surface. On the basis of the discrete sources method and the T-matrix method, numerical schemes were developed and implemented in computer programs. Numerical results related to the influence of particle shape on the scattering characteristics are discussed. We will show that even for particles much smaller than the wavelength the scattering characteristics are still sensitive to the particle shape. (C) 2000 Elsevier Science B.V. All rights reserved.
