We analyze the Goos–Hänchen (GH) shift and longitudinal spin splitting (LSS) at a planar interface between two optical media in the spin representation. While these optical effects have been studied previously, we examine the direct and cross-refl

The intrinsic connection between the transverse photonic spin Hall effect (PSHE) and the Imbert–Fedorov shift has been well characterized. However, physical insights into the longitudinal photonic spin splitting associated with the Goos-Hänchen (G

In this paper, we use the rotating elliptical Gaussian beams (REGBs) to impinge the surfaces coated with cross-anisotropic metasurfaces (CMs) to investigate the Goos–Hänchen (GH) and Imbert–Fedorov (IF) shifts. The effect of the CM coating on th

We introduce a theoretical research of the Goos-Hänchen (GH) and Imbert-Fedorov (IF) shifts for the rotating elliptical Gaussian beams (REGBs) incidencing on a weakly absorbing semi-infinite medium. We show that the rotation ellipse parameters a, b

We propose a novel and simple method for obtaining the giant longitudinal spin Hall effect (SHE) of the reflected light beam when the elliptically polarized light (instead of the linearly polarized light) at the telecommunication wavelength is obliqu

In this paper, the circle Bessel Gaussian vortex beams (CBGVBs) are introduced in a harmonic potential for the first time, whose autofocusing properties are explored by theoretical analysis as well as numerical simulation. According to the dimensionl

The Goos–Hanchen (GH) shift for the reflection of the elegant Hermite–Gauss beams (EHGBs) impinging on single-layer graphene-coated surfaces is theoretically studied. The factors influencing the GH shift, including the incident angle, the refract

In this work, we propose a graphene-indium tin oxide (ITO)/TiO2/ITO sandwich structure and theoretically study the Goos-Hänchen (GH) shift within the epsilon-near-zero region of the ITO. The findings show that the sign of GH shifts keeps positive or

The Goos-Hanchen (GH) shift of a Gaussian beam reflected from surfaces coated with a cross-anisotropic metasurface (CM) is theoretically investigated. It is revealed that, the CM coating has influence on the spatial GH shift as well as the angular on
