Abstract: Linear polarization characteristics of polydisperse, randomly oriented small ice crystals modeled by finite circular cylinders are calculated by using the T-matrix approach, with emphasis on the thermal infrared spectral region and extension from the atmospheric short-wave IR window to the far IRR wavelengths up to 30μm. The 31 particle size distributions and 10 cylindrical shapes are considered. The results of the extensive calculations show that the linear polarization of small ice cylindrical particles in IR region depend strongly on wavelengths and refractive indices, particle shapes and size distributions compared with the similar work in literature, some new and significant facts are obtained.
