Abstract

The WGM method was used in designed cryogenic dielectrometer for measurement of dielectric parameters of cryogenic liquids with small losses within the frequency range of 50-150 GHz and temperatures 0.8-300 K. The change of resonant characteristics of high-Q DDR, placed into He ⁴ at temperature lower the lambda-transition (a superfluid state) is detected
