Abstract

The coupled dipole method has been used to model the S34 scattering matrix element for particles of arbitrary shape. Comparison of the results of the approximate method with the exact theory for a sphere shows that the size of the units required for S34 is much smaller than the size required for calculating S11 with similar accuracy. Model calculations for chiral particles show that the S34 matrix element depends sensitively on the exact shape, size and optical properties of the scatterer.
