Magnetic field dependence of the coupling efficiency of a superconducting transmission line due to the proximity effect

Abstract

The coupling efficiency of a Nb superconducting transmission line has been measured using a Fourier transform spectrometer for different magnetic fields. It is found that the coupling decreases with increasing magnetic field when the frequency is close to the gap of the Nb superconductor. This is attributed to the changes of the surface impedance of the proximity-coupled superconductor/normal-metal bilayers in the transmission line.
