Suppression of radiation loss in high kinetic inductance superconducting co-planar waveguides

S. Hähnle, N. v. Marrewijk, A. Endo +4

We present a novel lab-on-chip technique to measure the very low losses in superconducting transmission lines at (sub-) mm wavelengths. The chips consist of a 100 nm thick NbTiN Co…
