During the past few years, metasurfaces have been used to demonstrate optical elements
and systems with capabilities that surpass those of conventional diffractive optics. Here, we …

In undergraduate courses on classical electromagnetism, it is taught that a perfect conductor
expels the electromagnetic (EM) field, and hence its surface is not able to support the …

Geometric metasurfaces primarily follow the physical mechanism of Pancharatnam–Berry
(PB) phases, empowering wavefront control of cross‐polarized reflective/transmissive light …

Metasurfaces are planar photonic elements composed of subwavelength nanostructures,
which can deeply interact with light and exploit new degrees of freedom (DOF) to manipulate …

In this paper, an all-dielectric InSb metasurface (MS) is proposed and investigated in
terahertz (THz) regime, which can achieve broadband thermal tunable reflective linear …

Metasurfaces, 2D artificial arrays of subwavelength elements, have attracted great interest
from the optical scientific community in recent years because they provide versatile …

In this work, we present an efficient polarization conversion device via using a hollow
graphene metasurface. The platform can simultaneously realize a series of excellent …

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 …

We propose a half wave plate in the terahertz region to realize broadband linear polarization
conversion in the reflection mode through anisotropic metamaterials. The structure of this …

Electromagnetic metastructures stand for the artificial structures with a characteristic size
smaller than the wavelength, which may efficiently manipulate the states of light. However …
