Breakdown of the effective medium theory: a perspective from Goos–Hänchen shift [PDF]

open access: yesNanophotonics
The effective medium theory (EMT) provides a simplified framework to calculate the electromagnetic responses and is generally considered exact in the all-dielectric system with deep-subwavelength constituents.

Graphene-Assisted Goos–Hänchen Shift in a Planar Multilayer Configuration in the Visible Light Range

open access: yesAdvances in Condensed Matter Physics, 2020
In this paper, the graphene-assisted Goos–Hänchen (GH) shift of the optical beam reflected from a planar multilayer configuration is investigated. The increased positive Goos–Hänchen shifts can be modulated by adjusting the Fermi energy due to graphene ...

Goos–Hänchen shift of inelastically scattered spin-wave beams and cascade nonlinear magnon processes [PDF]

open access: yesScientific Reports
We study, using micromagnetic simulations, the inelastic scattering of spin-wave beams on edge-localized spin-wave modes in a thin ferromagnetic film.

Polarization-Modulated, Goos–Hanchen Shift Sensing for Common Mode Drift Suppression [PDF]

open access: yesSensors, 2019
A polarization-modulation-based Goos−Hanchen (GH) sensing scheme leveraging the polarization-dependence of the Bloch surface wave enhanced GH shift is proposed and experimentally demonstrated.

Controllable large positive and negative Goos–Hänchen shifts with a double-Lambda atomic system [PDF]

open access: yesScientific Reports, 2023
We study the Goos–Hänchen shift (GHS) of a reflected light beam from a cavity containing a double- $$\Lambda$$ Λ atomic medium that is bounded by two glass slabs.

Large spatial Goos-Hänchen shifts from quasicrystals with graphene

open access: yesResults in Physics, 2020
We investigate the spatial Goos-Hänchen (GH) shift of reflected beam from quasicrystals composed of Fibonacci dielectrics and graphene. The quasicrystals are composed of two symmetrical Fibonacci dielectrics and graphene is embedded in the center of the ...

Tunable GH shift based on hyperbolic metamaterials composed of graphene and dielectric [PDF]

open access: yesScientific Reports
We theoretically analyze the enhancement and regulation of Goos-Hänchen (GH) shift in hyperbolic metamaterials in the near-infrared band. For a given incident wavelength, photonic crystals composed of graphene and dielectric present hyperbolic dispersion

The general treatment of giant Goos-Hänchen shift in a slab cavity

open access: yesJournal of Taibah University for Science, 2020
In this study, the general treatment to obtain negative/positive giant Goos-Hänchen shifts for a slab cavity is provided. We find that there are two main types of giant shifts: The first type (type I) is associated with near-zero reflection coefficient ...

Quantum reflection time and the Goos-Hänchen effect [PDF]

open access: yesPhysical Review Research
We explore the analogy between following the motion of a reflected wave packet and a quantum measurement of the spatial delay imposed on the particle by the scattering potential. It is shown that converting such delays into temporal durations can lead to
