“…Based on the results of [6,7] the conjecture was made that fresh ice may have specific electromagnetic properties at 0 • C. In the cited papers, additional electromagnetic waves of the same polarization as the original ones, but with a slightly different wave number value were observed during radio-raying of the ice covers.…”

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.

“…In particular, we have showed for the first time [5] that the socalled "additional" waves (or the Ginzburg-Pekar waves predicted in crystal optics [6,7]) appear in ice within a certain temperature interval around the icewater phase transition. These additional waves exhibit unique properties: possessing the same polarization as the initial wave, they have a somewhat different value of the wave vector (that is, of the wavelength) and a different phase velocity direction.…”

Phase increments of the coefficient of microwave reflection from the air-ice interface have been measured at a frequency of 13.8 GHz at temperatures in the vicinity of the ice-water phase transition. It is established that the phase of the reflection coefficient exhibits variations within several dozen degrees upon the appearance of the first signs of ice melting. This phenomenon has to be taken into account in interpreting the results of phase-sensitive radar probing for glacial objects. PACS numbers: 41.20.Jb
