Abstract. The paper discusses a new resonant method of frozen biological tissues dielectric properties determination at temperatures ranging from –20 to –1°C in the frequency band of 100–200 MHz under phase transition of the frozen water containing in tissue. For carrying out resonant measurements, a special measuring cavity cell has been developed. This method has been tested using water ice, which is prepared from distilled water and has a well-known dielectric constant. The dielectric parameters of the frozen sea trout back were also measured in the 100–200 MHz frequency band and compared with previously published data.
Key words: imperfect dielectric, frozen biological tissue, dielectric constant, dielectric losses, dielectric losses tangent angle, phase transitions, electromagnetic waves, very high frequencies, resonator measuring cell.
Financing: investigation was carried out as part of the State Assignment of the V.M. Gorbatov Federal Research Center for Food Systems of the RAS No. FGUS-2025-0004.
