Ultrafine metal filament systems and semiconductors that effectively absorb Ultra-High Frequency (UHF) radiation have been obtained. Research of high-frequency properties of these systems in the frequency range GHz at temperatures  was carried out. For ultrafine mercury filament, the temperature dependence of the absorption of UHF-radiation is not monotonous. It is found that the temperature dependence of the UHF-radiation absorption in these filaments in the field of superconducting transition and melting type transition is qualitatively different from the dependence observed for thicker filaments. The experimental results are interpreted based on the model of weak shielding of high-frequency fields in ultrafine conductors
