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
