Over the past decade, metasurfaces have attracted great interest in the global research
community due to their extraordinary performance parameters and electromagnetic …

Based on the principle of super-symmetric lens with quadratic phase gradient
transformation, combined with the principle of digital coding of metasurface, we propose a …

We propose a wideband linear polarization converter in transmission mode by bilayer
metamaterial. The polarization converter operates from 0.55 to 1.37 THz with polarization …

A pair of vortices, one of the multiple vortices, exhibits more adjustable parameters and
attractive characteristics compared with a single vortex. By introducing a vortex pair on the …

We examine the spin-orbit interaction of light and photonic spin Hall effect on the surface of
anisotropic two-dimensional atomic crystals. As an example, the photonic spin Hall effect on …

Optical sensing is crucial in many applications and has received widespread attention in
recent years. Transmission spectroscopy with narrow linewidth resonances is indispensable …

We show that a metasurface composed of a subwavelength metallic slit array embedded in
an asymmetric dielectric environment can exhibit either extraordinary optical transmission …

Diffraction of light of a visible spectral range by subwavelength metal gratings has been
investigated experimentally and theoretically using rigorous electromagnetic calculations. It …

Abstract we propose an anisotropic programmable coding metasurface, which is composed
of digital coding elements integrated with PIN diode. The" 0 ″and" 1 ″states of the diode …

A novel terahertz (THz) sensing scheme is proposed based on the photonic spin Hall effect
(PSHE). By illumining a paraxial Gaussian THz beam onto a black phosphorus (BP)-based …
