Effect of Goos Hänchen shift of the light transmitted through a mixture of the graphene hyperbolic metamaterial and 1D superconducting photonic crystals

Abstract

In this paper, the graphene hyperbolic metamaterial (GHMM) and one-dimensional (1D) superconductor (YBa2Cu3O7-x) photonic crystals are combined to observe the Goos Hänchen (GH) shift by studying the lateral shift under the TE wave in the terahertz (THz) regime. GHMM consists of a monolayer of graphene and a layer of conventional dielectric. It indicates that the proposed 1D dielectric structure can produce a larger GH shift. The movements of the GH shifts can be observed through tailoring the dielectric length and three parameters of graphene which are chemical potential, phenomenon scattering rate, and temperature, respectively. Moreover, the relationship between the GH shift and the real part of nG for the GHMM (RnG) also is studied. We find that altering the above four parameters to produce the larger GH shifts is mainly concentrated in the frequency range of 30-50 THz and 70- 90 THz, and the larger RnG can lead to the more obvious GH shift.
