In this work, using the prism method at a frequency of 37.5 GHz, an experimental study was made of the dependence of the refractive index of dry snow on bulk density in the range of its values 0.16–0.535 and particle sizes up to 10 mm. The studied snow samples had both self-formed and destroyed structures. In addition, various combinations of a mixture of pieces of fine-grained snow crust and large fragments of icicles were used. A comparative analysis of the experimental data obtained in this work with the known data showed that the dependence of the real part of the complex permittivity of dry snow on the bulk density is described by the Polder – van Santen formula, regardless of the snow structure, with particle sizes at least comparable with the wavelength.
Keywords: dry snow, refractive index, bulk density, wavelength-comparable ice particles, experiment, prism method
