Перспективы развития фундаментальных наук. Т. 3 : сборник научных трудов XV Международной конференции студентов, аспирантов и молодых ученых, 24-27 апреля 2018 г Т. 3 : Математика. С. 108-110Abstract: The paper presents optical characteristics obtained using the normal distribution and the gamma distribution lows with respect to the distortion angle of the hexagonal ice columns. The results are obtained within the physical optics approximation for hexagonal ice columns with lengths of 10, 31.62, 100, 316.23, 562.34, 1000 microns and diameters of 7, 22.14, 69.6, 123.77, 165.05 and 220.09 microns, respectively. The calculations were carried out for the wavelengths of 532 and 1064 nm, the refractive index was assumed to be 1.3116 and 1.3004, respectively. The distortion angle of the right dihedral angle ran within the range of 0° (regular particle) to 10°. The results obtained using the chosen model of column shape distortion showed better agreement with experimental observations, as compared to the calculations obtained for regular columns.
