The concept of metamaterials originates from the proposal of left-hand materials with
negative refractive index, followed by which, varieties of metamaterials with kinds of fantastic …

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

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 …

High absorption efficiency is particularly desirable at present for various microtechnological
applications including microbolometers, photodectors, coherent thermal emitters, and solar …

We theoretically and numerically study the absorption effect and the heat generation in
plasmonic metamaterials under light radiation at their plasmonic resonance. Three different …

We experimentally demonstrate the absorption properties of designed metamaterial
absorbers in the near-infrared wavelength regime. For the rectangular-shaped case, we …

Localized plasmons formed in ultrathin metallic nanogaps can lead to robust absorption of
incident light. Plasmonic metasurfaces based on this effect can efficiently generate energetic …

The electromagnetic wave propagation of a two-dimensional optical black hole with graded
index photonic crystals for transverse magnetic modes is studied. The implementation of the …

In this paper, three different unit cells are designed on the basis split-ring-cross resonators,
and each unit cell has an absorption rate greater than 90% at incident angles of 0°, 30°, and …

We propose a design and numerical study of an optically switchable metamaterial absorber
in the terahertz regime. The metamaterial absorber comprises a periodic array of metallic …
