Goos-Hänchen shift in silicene
Results in Physics, 2021 Silicene has a rich phase diagram, which is due to the strong spin–orbit coupling induced by the buckled structure. In this work, the Goos-Hänchen (GH) shift of silicene in different phases is investigated.

Magnonic Goos–Hänchen Effect Induced by 1D Solitons [PDF]
, 2022 The spin wave spectral problem is solved in terms of the spectrum of a diagonalizable operator for a class of magnetic states that includes several types of domain walls and the chiral solitons of monoaxial helimagnets. Focusing on these latter solitons,

On anomalous optical beam shifts at near-normal incidence
APL Photonics, 2022 We develop the theory of optical beam shifts (both Goos–Hänchen and Imbert–Fedorov) for the case of near-normal incidence, when the incident angle becomes comparable with the angular beam divergence.

Exploration of Illicit Drug Detection Based on Goos–Hänchen Shift
Photonics, 2023 Amidst the escalating issue of drug abuse, an urgent need for effective illicit drug detection methods has arisen. This paper introduces a novel optical approach utilizing the Goos–Hänchen Shift (GHS) to explore the possibility of on-site rapid detection

Ultranarrow polaritonic cavities formed by one-dimensional junctions of two-dimensional in-plane heterostructures. [PDF]
NanophotonicsAbstract We propose two‐dimensional (2D) in‐plane heterostructures, composed of a 2D crystal adjoining a perfect electric conductor (PEC) plane, that enable ultranarrow polaritonic resonant cavities. Specifically, we theoretically investigate the interaction of 2D surface polaritons (2DSPs) with the junction between the 2D crystal and a PEC plane.

Enhanced Goos-Hänchen shift of graphene coated on one-dimensional photonic crystal
Results in Physics, 2020 The enhancement of Goos-Hänchen shift of graphene coated on a truncated one-dimensional photonic crystal is proposed and theoretically investigated. The proposed band-gap configuration featuring highly electric field enhancement and confinement on the ...

Deep-subwavelength engineering of stealthy hyperuniformity. [PDF]
NanophotonicsAbstract Light behaviours in disordered materials have been of research interest primarily at length scales beyond or comparable to the wavelength of light, because order and disorder are often believed to be almost indistinguishable in the subwavelength regime according to effective medium theory (EMT).

Photonics, 2022 For optical beams transmitted by a right-angle prism, the Goos–Hänchen shift can never be seen as a pure effect. Indeed, the lateral displacement, caused by the total internal reflection, will always be accompanied by angular deviations generated by the ...
