Goos-Hänchen and Imbert-Fedorov shifts for Gaussian beams impinging on graphene-coated surfaces.
We present a theoretical study of the Goos-Hänchen and Imbert-Fedorov shifts for a fundamental Gaussian beam impinging on a surface coated with a single layer of graphene. We show that the graphene surface conductivity σ(ω) is responsible for the appearance of a giant and negative spatial Goos-Hänchen shift.
متن کاملGoos-Hänchen and Imbert-Fedorov shifts of polarized vortex beams.
We study, analytically and numerically, reflection and transmission of an arbitrarily polarized vortex beam on an interface separating two dielectric media and derive general expressions for linear and angular Goos-Hänchen (GH) and Imbert-Fedorov shifts. We predict a novel vortex-induced GH shift and also reveal a direct connection between the spin-induced angular shifts and the vortex-induced ...
متن کاملGiant Goos-Hänchen shifts and radiation-induced trapping of Helmholtz solitons at nonlinear interfaces.
Giant Goos-Hänchen shifts and radiation-induced trapping are studied at the planar boundary separating two focusing Kerr media within the framework of the Helmholtz theory. The analysis, valid for all angles of incidence, reveals that interfaces exhibiting linear external refraction can also accommodate both phenomena. Numerical evidence of these effects is provided, based on analytical predict...
متن کاملObservation of giant Goos-Hänchen and angular shifts at designed metasurfaces
Metasurfaces with sub-wavelength features are useful in modulating the phase, amplitude or polarization of electromagnetic fields. While several applications are reported for light manipulation and control, the sharp phase changes would be useful in enhancing the beam shifts at reflection from a metasurface. In designed periodic patterns on metal film, at surface plasmon resonance, we demonstra...
