Superconducting Microstrip Losses at Microwave and Sub-millimeter wavelengths
S. Hähnle, K. Kouwenhoven, B. Buijtendorp +5
We present a lab-on-chip experiment to accurately measure losses of superconducting microstrip lines at microwave and sub-mm wavelengths. The microstrips are fabricated from NbTiN,…
