A tunable light absorption of graphene using topological interface states (TISs) is presented.
The monolayer graphene is embedded in the interface of asymmetric topological photonic …

Recently, terahertz (THz) nonreciprocal and functionality-switchable devices have drawn
much attention. Here we report a magnetic-free THz unidirectional perfect absorber as well …

Metasurfaces that can operate without a strictly periodic arrangement of meta-atoms are
highly desirable for practical optical micro-nano devices. In this paper, we propose two kinds …

The tunable plasmon induced reflectance (PIR) effect has been numerically investigated
and experimentally realized by hybrid metal-graphene metamaterials. The PIR effect is …

A magnetic mirror operating in the terahertz band is designed based on the functional
reflective metasurface, which is simply constructed by a one-dimensional periodic lithium …

This paper presents dual-band high-gain subwavelength cavity antennas with artificial
magnetic conductor (AMC) metamaterial microstructures. We developed an AMC …

We present a specific subwavelength-cavity high-gain circularly polarized ultra-thin antenna
made of planar metamaterials. The antenna is designed to operate at 2.80 GHz with a fixed …

Common optical metasurfaces are two-dimensional functional devices composed of
periodically arranged subwavelength constituents. Here, we achieved the positional …

Functional tunability, environmental adaptability, and easy fabrication are highly desired
properties in metasurfaces. Here we provide a tunable bilayer metasurface composed of two …

We present a kind of large area subwavelength cavity antenna with artificial permeability-
negative metamaterials at GHz range. The antenna has the advantages of flatness, ultra-thin …
