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 absorbers have drawn increasing attention in many areas. A series of
plasmonic and metamaterial structures can work as efficient narrowband absorbers due to …

A dual-band terahertz metamaterial absorber composed of two identical square metallic
patches and an insulating medium layer on top of a continuous metallic ground is …

The advent of negative index materials has spawned extensive research into metamaterials
over the past decade. Metamaterials are attractive not only for their exotic electromagnetic …

Recent advances in nanofabrication and characterization technologies have spurred many
breakthroughs in the field of optical metamaterials and metasurfaces that provide novel …

Surface plasmons generated at the graphene dielectric interface can be altered by trapping
the electric charge. A technique is implemented for trapping the bipolar electric charge on …

We present an ultrabroadband thin-film infrared absorber made of sawtoothed anisotropic
metamaterial. Absorptivity of higher than 95% at normal incidence is supported in a wide …

We present a simple dual band absorber design and investigate it in the terahertz (THz)
region. The proposed absorber works in dual operating bands at 5.1 THz and 11.7 THz. By …

We report a broadband polarization-independent perfect absorber with wide-angle near
unity absorbance in the visible regime. Our structure is composed of an array of thin Au …

In this paper, we present an active controllable terahertz absorber with dual broadband
characteristics, comprised by two diagonal identical patterns of vanadium dioxide in the top …
