We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …

With recent advances in nanophotonics and nanofabrication, considerable progress has
been achieved in realizations of thin composite layers designed for full absorption of …

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 …

Metamaterials are typically engineered by arranging a set of small scatterers or apertures in
a regular array throughout a region of space, thus obtaining some desirable bulk …

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

Energy of propagating electromagnetic waves can be fully absorbed in a thin lossy layer, but
only in a narrow frequency band, as follows from the causality principle. On the other hand, it …

An efficient approach to achieve the shielding effectiveness (SE) by using a frequency-
selective surface (FSS) is presented. This FSS, which consists of cross dipoles and rings …

In this paper, a novel and miniaturized band-stop frequency selective surface (FSS) is
presented. This FSS provides effective shielding in X-band, with attenuation of at least 56 …

Gradient metasurfaces (GMs) can provide pre-defined wave vectors that are along the
surface of GMs. When the additional wave vector is greater than that of incident waves, the …

We design a terahertz (THz) metamaterial absorber having four narrowband high
absorptivities of 98%, 97%, 98% and 97% at frequencies of 0.68 THz, 1.27 THz, 2.21 THz …
