A four-band terahertz tunable narrow-band perfect absorber based on a bulk Dirac semi-
metallic (BDS) metamaterial with a microstructure is designed. The three-layer structure of …

We numerically demonstrate an optically switchable broadband metasurface absorber
(MSA) structure based on planar patterned photoconductive silicon (Si) in terahertz (THz) …

In this paper, for improving the refractive index sensitivity, we propose different sensor
devices by optical metamaterial nanoabsorbers. The presented absorbers are designed by …

In this work, we propose an ultra-wideband and wide-angle optically transparent flexible
metamaterial absorber (MMA), consisting of a multilayered structure with a transparent …

Herein, we propose an all dielectric, open-slit, U-shaped resonant arm-based metasurface
that achieves three bound states in the continuum (BIC) in the high-frequency terahertz band …

We proposed a polarization-insensitive absorber based on strontium titanate (STO) and bulk
Dirac semimetal (BDS) in the terahertz (THz) region. The center frequency of the absorption …

Tunable terahertz (THz) absorber is a hot research topic in recent years. However,
absorption peak number control is rarely studied. A multi-band THz absorber based on a …

Material science at the beginning of the twenty-first century has largely been dominated by
the study of graphene and other Dirac-type materials. Interesting physics manifest in the …

Terahertz (THz) waves possess unique characteristics such as high transmission, strong
absorption, and low photon energy. THz metamaterial sensors, as label-free and rapid …

Excellent characteristics and promising application prospects promote the rapid
development of metamaterials. We have numerically proposed and demonstrated a novel …
