Measurements of Electrodynamic Parameters at Low Temperatures in the Frequency Range up to 18 GHz

The paper describes a method for measuring electrodynamic parameters in the frequency range from 10 MHz to 18 GHz at temperatures up to -180 °C. The measurement results are given for an empty transmission line and the line filled with the test material. Frequency dependences of the S-parameters depending on the sample temperature are shown.
