Zubko, E., Y. Shkuratov, M. Mishchenko, and G. Videen, 2008: Light scattering in a finite multi-particle system. J. Quant. Spectrosc. Radiat. Transfer, 109, 2195-2206, doi:10.1016/j.jqsrt.2008.03.007.

We use the discrete dipole approximation (DDA) to perform electromagnetic scattering calculations of particles in a 3D volume. We adjust the spacing between the particles to change the volume densities of the scattering systems from approximately 10 to 100%. For very large volume densities, e.g. >50%, it is difficult to assign unambiguously whether the system is composed of a single heterogeneous particle or of multiple particles. Our calculations demonstrate optical effects attributable to multiple scattering in systems having volume densities as high as ∼90%. This suggests that heterogeneities within naturally occurring particle systems can produce multiple-scattering effects. We also see evidence of very deep negative polarization branches (∼ -6%) that may have implications in interpreting polarization phase curves of cometary circumnuclear halos.
