Metasurfaces have attracted great attention due to their ability to manipulate the phase,
amplitude, and polarization of light in a compact form. Tunable metasurfaces have been …

A meta‐lens is an advanced flat optical device composed of artificial antennas. The
amplitude, phase, and polarization of incident light can be engineered to satisfy the …

A novel hierarchical re-entrant honeycomb metamaterial is proposed by integrating the re-
entrant honeycomb (RH) with square unit cell and named as square re-entrant honeycomb …

Bound states in the continuum (BICs) with infinite quality factor (Q-factor) and significant field
enhancement pave the way for realizing highly sensitive optical sensors with enhanced light …

An auxetic metamaterial consisting of a re-entrant honeycomb structure with hierarchical
characteristics (RHS-H) is proposed. The new structure is constructed by attaching small re …

A novel type of tubular structure has been proposed in this paper, which is the first tubular
structure with auxeticity in the wall thickness as well as in the radial direction. This tubular …

We demonstrate a dual-band plasmonic perfect absorber (PA) based on graphene
metamaterials. Two absorption peaks (22.5 μm and 74.5 μm) with the maximal absorption of …

In this paper, we propose a graphene nanoribbon-ring cross structure. A multi-band
absorber is obtained by a simple combination of graphene nanoribbons and and graphene …

A triple-band perfect metamaterial absorber based on periodically arranged graphene split
ring resonator (SRR) is proposed in this study. The calculation results by the FDTD method …

The combination of graphene and a metasurface holds great promise for dynamic
manipulation of the electromagnetic wave from low terahertz to mid-infrared. The optical …
