Abstract

The temperature dependence of the wave propagation in superconducting striplines from 80 to 100 GHz is experimentally examined for the first time. The measured resonance frequency spacing and temperature shift are in good agreement with theoretical predictions. The loss measurements are limited by SNR in the setup, and an upper limit of 0.01-0.02 of dielectric loss tangent is estimated near 80 GHz from 1.6K to 4.2K.
