Terahertz (THz) science and technology have greatly progressed over the past two decades
to a point where the THz region of the electromagnetic spectrum is now a mature research …

In this paper, an active tunable terahertz bandwidth absorber based on single-layer
graphene is proposed, which consists of a graphene layer, a photo crystal plate, and a gold …

Surface‐enhanced infrared absorption spectroscopy (SEIRA) has emerged as a powerful
technique for ultrasensitive chemical‐specific analysis. SEIRA can be realized by employing …

Terahertz (THz) imaging can see through otherwise opaque materials. However, because of
the long wavelengths of THz radiation (λ= 400 μm at 0.75 THz), far-field THz imaging …

Terahertz metasurface biosensors have gained significant attention in biological field due to
its label-free, real-time and in-situ detection properties. In this paper, a planar array of Fano …

The nonlinear optical response of materials allows optical functionality not seen in linear
devices, such as switching, wavelength conversion, and adaptive optics. Unfortunately, the …

In this paper, a dual-band perfect metamaterial absorber based on graphene is proposed in
the terahertz region. The metamaterial absorber consists of two sizes of graphene disks and …

High‐index dielectric subwavelength structures and metasurfaces are capable of enhancing
light‐matter interaction by orders of magnitude via geometry‐dependent optical resonances …

A broadband metamaterial absorber with a single layer of tantalum nitride (Ta 2 N 3)
frequency selective surface layer, printed on a foam substrate, is presented. The proposed …

A tunable metamaterial absorber composed of a metal ground plane, a SiO 2 dielectric
spacer, a graphene layer and a metal pattern layer, which is polarization sensitive is …
