Metamaterials (MM) are artificially designed materials that possess unique properties due to
their geometrical design. They also display some peculiar properties, such as negative …

In this paper, we propose a highly sensitive, four-band, high-frequency detector with a
perfectly tunable absorber based on Dirac semimetals. The design architecture relies on a …

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 SiO_2 dielectric …

Hybrid metamaterials that exhibit reconfigurable responses under external stimulus, such as
electric fields and light radiation, have only recently been demonstrated by combining active …

We present a new type of dual-band terahertz metamaterial absorber formed by a patterned
metallic strip and a dielectric layer on top of a metallic ground plane. It is found that besides …

A new type of quad-band terahertz metamaterial absorber based on a common sandwich
structure is investigated. In sharp contrast to the most previous studies focused on only …

We present a four-band and polarization-insensitive terahertz metamaterial absorber formed
by four square metallic rings and a metallic ground plane separated by a dielectric layer. It is …

For a general metamaterial absorber, single patterned structure has only one resonance
absorption peak. Therefore, a multi-band perfect absorber can be obtained by employing …

In this paper, a bulk Dirac semimetals (BDSs) based tunable narrowband absorber at
terahertz frequencies is proposed and it has the attractive property of being polarization …

A broadband tunable metamaterial graphene absorber is investigated in this paper. The unit
cell of the proposed metamaterial graphene absorber is composed of four patch resonators …
