Spatial and angular shifts of terahertz wave for the graphene metamaterial structure

Influence of misfit strain on the Goos–Hänchen shift upon reflection from a magnetic film on a nonmagnetic substrate

“…Beyond their fundamental interest, Goos-Hänchen-like lateral shifts upon reflection or transmission of a light beam, as well as the related Imbert-Fedorov effect (i.e., a beam shift in the direction perpendicular to the plane of incidence), have become relevant in technological domains, as illustrated by recent review papers [9,10]. They have been shown to affect the propagation modes in optical waveguides or microcavities [11] designed for photonic applications, and have also been studied in many types of structures, including electro-optic [12][13][14][15] or magneto-optic materials [16][17][18][19][20][21], photonic crystals [22][23][24], superconducting multilayers [25,26], plasmonic structures [27][28][29], graphene [30][31][32], at the interface between an ordinary dielectric and a topological insulator [33], as well as in metamaterials [34][35][36][37][38]. Recently the Goos-Hänchen effect has been studied for partially coherent light fields [39] and in a standing-wave-coupled electromagnetically-inducedtransparency medium [40,41].…”

Scattering of surface plasmon polaritons in a graphene multilayer photonic crystal with inhomogeneous doping

“…In practice, these graphene multilayers can be used as terahertz modulators 34 , broadband polarizers 35 , tunable Bragg reflectors 7 , and polarization splitters 20 . Also it is interesting that the graphene stacks exhibit the properties of hyperbolic metamaterials [36][37][38] . Finally, the study of propagation of radiation in a disordered graphene stack when light impinges perpendicularly to the graphene surface has recently been considered 17 , showing that graphene can control Anderson localization of radiation.…”

Numerical study of biosensor based on α-MoO3/Au hyperbolic metamaterial at visible frequencies

“…The GH shift occurs at the interface of two materials with different permittivity and manifests lateral shift displacement when the incident angle is close to the critical angle. To date, GH shifts have been reported in various systems, including parity-time-symmetry cavity [38,39], photonic crystals [40,41], graphene [16,[42][43][44][45] and metamaterials [46][47][48]. Since order of magnitude of the GH shifts is normally based on the operating wavelength, the GH shifts present a small lateral shift at visible frequency and are hard to observe directly.…”

“…Au and Ag along with dielectric materials such as Al 2 O 3 and TiO 2 are common choices for HMMs. In addition, integrating with tunable materials such as graphene [8,[16][17][18], topological insulators [14,19] and phase-change materials [20][21][22], active HMMs can be achieved. However, most of the research works about active HMMs have focused on infrared and terahertz frequency regions [8,14,17,19,20].…”
