Metamaterial absorbers have been widely studied and continuously concerned owing to
their excellent resonance features of ultra‐thin thickness, light‐weight, and high absorbance …

This work reviews fundamentals and the recent state-of-art achievements in the field of
plasmonic biosensing based terahertz (THz) spectroscopy. Being nonpoisonous and …

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 …

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

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 …

Imaging in the terahertz (THz) range of the electromagnetic spectrum is difficult owing to the
lack of high-power sources and efficient detectors. For decades, there has been tremendous …

We report the design, fabrication, and measurement of a microwave triple-band absorber.
The compact single unit cell consists of three nested electric closed-ring resonators and a …

We propose a dual-controlled switchable broadband terahertz (THz) metamaterial absorber
based on a hybrid of vanadium dioxide (VO_2) and graphene that demonstrates strong …

This review aims to summarise the progress in some materials and structures for
electromagnetic applications, such as microwave absorption, electric shielding and antenna …
