Annotation The possibility of using microwave measurement technique to study the processes taking place in ice and porous media containing water during cooling and heating was investigated. Two methods were considered: waveguide and radiometric. The basis of these methods is the following: there is a significant difference in the absorption coefficient of electromagnetic waves for water and ice, and it is not difficult to study the water - ice phase transitions. It is also possible to study media in a different state in a confined space, in a waveguide and in free space by a radiometric method. Two examples of the application of these techniques are presented. As follows from the results of the experiments carried out, there are differences in the nature of the eutectic processes that can occur due to the stressed state of the sample when ice forms in the closed space and free space.
Key words phase transition, ice, microwave radiation, hysteresis, absorption coefficient, eutectic point, loss factor
