Multiple-frequency-band metamaterial absorbers possess great application prospects,
which are usually achieved by vertically stacking or coplanar arranging several sub …

We numerically demonstrate a tunable dual-band terahertz metamaterial absorber (MA) with
near-unity absorption using single-layer square graphene ring structure with T-shaped …

Perfect solar energy absorption is becoming more and more significant in the fields of
carbon neutrality, the numerical study of various metamaterial solar absorbers is boosting …

In this work, we propose two different graphene-covered nanostructured metamaterial
absorbers inspired by Penrose tiling. These absorbers allow spectrally tunable absorption …

We present a simple design for a broadband tunable terahertz metasurface absorber (MSA),
which is composed of a periodic array of complementary-wheel-shaped (CWS) graphene …

Graphene has attracted considerable attention ever since the discovery of its unprecedented
properties, including its extraordinary and tunable electronic and optical properties. In …

A multifunctional metasurface based on graphene and vanadium dioxide (VO 2), which can
function as a broadband absorber, half-wave plate (HWP), and quarter-wave plate (QWP) in …

Investigation was made of the optical response of metal-dielectric stacks-based cavity
structures embedded with graphene microheaters for the purpose of perfect absorption. The …

We propose a graphene-dielectric hybrid metamaterial (GDHM) that supports the quasi-
bound state in the continuum (BIC). By rotating one of the LiTaO 3 bars, the quasi-BIC …

This paper presents a graphene-based tunable polarization-insensitive metamaterial
absorber (MMA) at terahertz (THz) frequencies. The absorber consists of top patterned gold …
