Abstract

In this work light absorption effect for atmospheric ice crystals for near-infrared electromagnetic spectrum is presented. The software for calculating the scattering matrices was modified for a crystal with absorption. The dependence of the M11 element of the scattering matrix on the zenith angle has been received within the physical optics approximation for three wavelengths: 0.532 μm, 1.064 μm, 1.6 μm, for convex and non-convex crystals, and for two conditions: with absorption factor and without it. The comparison of the M11 element of the scattering matrix for these conditions shows negligible changing of intensity for 0.532 μm and 1.064 μm wavelengths and significant decrease of intensity for 1.6 μm.
