Application of hyperbolic metamaterial based on graphene-superconductor in temperature sensor

Abstract

The invention provides an application of a hyperbolic metamaterial based on a graphene-superconductor in a temperature sensor, and belongs to the technical field of temperature sensors. The hyperbolic superconducting material is a hyperbolic metamaterial with a periodic structure formed by alternately arranging graphene and superconductors; in a low-temperature environment, after light waves are incident to the hyperbolic superconducting material by adjusting the Fermi level of the graphene, the number of layers of the graphene, the thickness of the superconductor and the environment temperature, large Goos-Hanchen (Goos-# imgabs0 #: GH) displacement is achieved near a phase transformation point from elliptic dispersion to hyperbolic dispersion, and the hyperbolic superconducting material is obtained. The corresponding relation between the GH displacement in the hyperbolic metamaterial and the environment temperature is applied to the low-temperature temperature sensor.
