Dispersive Fourier Transform Spectrometer for Characterizing superconducting NbTiN films at THz frequencies

OSA Optical Sensors and Sensing Congress 2021 (AIS, FTS, HISE, SENSORS, ES), pp. FW3D.5

Abstract

A Terahertz Dispersive Fourier Transform Spectrometer was used to study the RF properties of superconducting films used for THz detectors. The experimental results were fitted using an extended Mattis-Bardeen theory and show a good agreement.
