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 th e scattering by a non-axisymmetric structure consisting of a nonspherical p article and a plane surface. On the basis of the discrete sources method an d the T-matrix method, numerical schemes were developed and implemented in computer programs. Numerical results related to the influence of particle s hape on the scattering characteristics are discussed. We will show that eve n for particles much smaller than the wavelength the scattering characteris tics are still sensitive to the particle shape. (C) 2000 Elsevier Science B .V. All rights reserved.
