Transmittance of electromagnetic radiation of the visible range by a thin film of ice 0 condensed on a dielectric substrate

The transmittance of electromagnetic radiation of the visible range through transparent dielectric samples with an ice nanolayer on their surface has been measured. Ice has been obtained by deposition of water vapor at a temperature of -170$^\circ$C to 0$^\circ$C. A decrease in the intensity of transmitted radiation at a wavelength of 0.52 $\mu$m by a factor of at least 2 depending on the material of the substrate and the temperature with a minimum near -23$^\circ$C has been revealed. This effect is assumingly due to the formation of ferroelectric ice 0 and surface plasmons in a highly conducting thin layer at the ice 0-insulator interface.
