Abstract

We used the discrete dipole approximation to study the backscattering of agglomerate particles consisting of oblong monomers. We varied the aspect ratio of the monomers from approximately 1 (sphere) to 4, while we kept the total particle volume equivalent to that of an x=10 sphere for m=1.59+i0 and 1.50+i0 and considered two values of agglomerate packing density: ρ=0.25 and ρ=0.1. We found that these particles do not display a prominent brightness opposition effect but do produce significant negative polarization over a range of near-backscattering angles. Increasing the monomers’ aspect ratio can make the negative polarization much more prominent. We have noted also that decreasing m and ρ can reduce the amplitude of the negative polarization for these particles.
