We study the light scattering properties of random ballisti c aggregates constructed in Shen et al. (Paper I). Using the discrete-dipole-approximation, we compute the s cattering phase function and linear polarization for random aggregates with various sizes and porosities, and wi th t o different compositions: 100% silicate and 50% silicate-50% graphite. We investigate the dependence o f light scattering properties on wavelength, cluster size and porosity using these aggregate models. We find… CONTINUE READING
