Metamaterial Coupling to the Superconducting Josephson Plasma Resonance in La<sub>2-x</sub>Sr<sub>x</sub>CuO<sub>4</sub>

ORAL

Abstract

The Josephson plasma resonance (JPR) in layered high temperature superconducting cuprates provides a useful probe of the superconducting condensate. We apply a series of interchangeable metamaterial tapes (consisting of arrays of split ring resonators (SRR)) to a c-axis single crystal of La2-xSrxCuO4 to investigate the electromagnetic coupling of the LC resonance of the SRR arrays with the JPR. We performed FTIR reflection measurements on these hybrid superconducting metamaterials below Tc=32K to search for anti-crossing behavior characteristic of strong coupling. This work informs future possibilities for optimizing the coupling strength of hybrid superconducting metamaterials and investigating nonlinear superconductivity under high field terahertz excitation.
