“…However, there exists another manifestation of the anomaly near the ice-water phase transition point, which is due to the occurrence of a through electric conductance over the water films, especially at the percolation point [12]. This anomaly is determined by the features of the electric properties of the water films.…”

“…In the third procedure, we explored the ice parameters by measuring the amplitude of a 3.3-GHz signal transmitted through a rectangular half-wave H 101 -mode resonator, which was completely filled up with ice. The measurement procedure with the use of an R2-56 gauge is presented in [12]. For the measurements, we took ice from fresh-water lakes and cut slabs out of the ice cover with salt content 3-5 mg/kg at a temperature of −(20-30) • C.…”

538.566We study phase variations in the coefficient of reflection from a flat air-ice boundary at the ice melting point. The measurements were performed by different methods at frequencies 3.3, 6, 13, and 32 GHz. The experimental data were compared with simple theoretical models. It was found that ice wettening in thin layers leads to a phase variation in the reflection coefficient by up to a few ten degrees with satisfactory agreement between the experiment and the theory. However, anomalies of the transmission properties of the samples unexplainable in terms of the model of effective dielectric permittivity of the melting layers were observed in a narrow temperature range before the ice destruction.
