Abstract : The presence of near-infrared (NIR) emission feature at 10 micron is well known in the circumstellar dust of O and C-rich stars observed by the Infrared Astronomical Satellite (IRAS) and Spitzer satellites and has been modelled by many workers including us in the recent past. The NIR polarization observations from such objects also show similar peak features in this region. This work describes some initial attempts to model these polarization features using non-spherical dust grains with mixture of silicates and other compositions and light scattering tools.
