The recent rise of metamaterials opens new opportunities for absorbers due to their
designed electrodynamic properties and effects, allowing the creation of materials with …

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

This paper presents a novel graphene-based proportional structure for a tunable wideband
absorber in the terahertz (THz) frequency range. In order to achieve the ideal design …

A dual-tunable metamaterial absorption modulator is proposed based on a hybrid vanadium
dioxide-graphene configuration. When vanadium dioxide is in the state of metal, the design …

Electromagnetic (EM) wave absorption plays a vital role in photonics. While metasurfaces
are proposed to absorb EM waves efficiently, most of them exhibit limited bandwidth and …

In this paper, a dual-band perfect absorber, composed of a periodically patterned elliptical
nanodisk graphene structure and a metal ground plane spaced by a thin SiO2 dielectric …

We present the simulation, implementation, and measurement of a broadband terahertz
(THz) metamaterial absorber. By stacking 12 metallic bars of varying lengths on three …

We propose a dual-controlled switchable broadband terahertz (THz) metamaterial absorber
based on a hybrid of vanadium dioxide (VO_2) and graphene that demonstrates strong …

A switchable graphene-based terahertz metamaterial absorber is proposed by using
nonstructured graphene loaded with simple dielectric resonators, which can achieve both …

We present a simple design of a broadband tunable metamaterial absorber (MMA) in the
terahertz (THz) region, which consists of a single layer complementary gammadion-shaped …
