Abstract: A superconducting medium includes a first layer made of a first superconductor and a second layer made of a second superconductor. The first layer has a first thickness less than a first coherence length of the first superconductor. The second layer has a second thickness less than a second coherence length of the second superconductor so as to induce a proximity effect between the first layer and the second layer. The proximity effect can induce desirable properties in the resulting superconducting medium. Controlling the thickness ratio of the first layer to the second layer can also tune the property of the superconducting medium.
