MgB2 and NbTiN-based hyperbolic metamaterial superconductors

POSTER

Abstract

Recent experiments have demonstrated that the metamaterial dielectric function engineering is capable of enhancing superconducting properties, such as tripling the critical temperature Tc in Al-Al2O3 epsilon near zero (ENZ) core-shell metamaterial superconductors. Similar effects have been observed in hyperbolic (superconductor/dielectric) metamaterials. In order to expand this approach to superconductors with higher Tc, MgB2/MgO, MgB2/AlN, and NbTiN/AlN multilayers were fabricated. Dielectric constants of these metamaterials measured via polarization reflectometry will be reported. Correlation of the results of the transport measurements and the hyperbolic properties of the multilayers will be discussed.
