Abstract: The observed line polarization in SNe is suggestive of chemical inhomogeneities (“clumps") in the layers above the photosphere. To explore spectropolarimetric signatures of clumps in SN ejecta, we have developed a fast, flexible, approximate, semi-analytic code for modeling polarized line radiative transfer within 3-D inhomogeneous rapidly-expanding atmospheres. We present results for the first part of our survey of model geometries, specifically the effects of clump covering fraction and number of clumps, on the emergent spectrum.
