Abstract
Measurements of the attenuation of electromagnetic radiation in supercooled water in the wavelength range from 0.2 to 3.0 cm with its supercooling to a temperature of about -70 °C are performed. Nanoporous materials were used to achieve deep supercooling. In such materials, the properties of pore water are close to those of bulk water. The measurements made it possible to derive a formula for the attenuation coefficient of supercooled water at temperatures below -30 °C. With the use of new data, calculations of the linear attenuation of electromagnetic radiation in the millimeter wavelength range at low temperatures for wet aerosols with small electromagnetic losses of the particle material were performed.
