Theoretical modeling of critical temperature increase in metamaterial superconductors
Recent experiments have demonstrated that the metamaterial approach is capable of a drastic increase of the critical temperature ${T}_{\mathrm{c}}$ of epsilon near zero (ENZ) metamaterial superconductors. For example, tripling of the critical temperature has been observed in $\mathrm{Al}\ensuremath{-}\mathrm{A}{\mathrm{l}}_{2}{\mathrm{O}}_{3}$ ENZ core-shell metamaterials. Here, we perform theoretical modeling of ${T}_{\mathrm{c}}$ increase in …
