ABSTRACT
A new approach to calculate the optical characteristics of axisymmetric
particles is developed. The electromagnetic fields are divided in two
(axisymmetric and non-axisymmetric) parts. The scattering problem is
formulated in the integral form and is solved separately for each
of the parts using specially chosen scalar potentials. The potentials
are expanded in terms of the spherical wave functions, and the expansion
coefficients are determined from solution of the infinite systems of
linear algebraic equations. Applicability of the suggested approach
to solution of the light scattering problem for Chebyshev particles,
spheroids and infinite circular cylinders is briefly discussed and
some results of calculations performed for these particles are given.
