Sub-wavelength superconducting rf meta-materials have evident advantages over their normal metal counterparts for strong diamagnetism, low-loss and intrinsically nonlinear tunability with temperature, dc magnetic, and rf electromagnetic field. We have demonstrated a nonlinear meta-material that can be switched between low and high transmission by controlling the power level of the incident beam. The origin of this nonlinear response is the superconducting Nb thin film employed in the meta-material structure. We show that with moderate RF power is possible to quench the superconducting state as a result of extremely strong current densities at the corners of the meta-material’s split-ring resonators. We measure a transmission contrast of 10 dB and a change in group delay of 70 ns between the low and high power states.
