During the past few years, metasurfaces have been used to demonstrate optical elements
and systems with capabilities that surpass those of conventional diffractive optics. Here, we …

Conventional optical components such as lenses, waveplates and holograms rely on light
propagation over distances much larger than the wavelength to shape wavefronts. In this …

Metasurfaces, two-dimensional equivalents of metamaterials, are engineered surfaces
consisting of deep subwavelength features that have full control of the electromagnetic …

Metasurfaces are a topic of significant research and are used in various applications due to
their unique ability to manipulate electromagnetic waves in microwave and optical …

One of the fundamental hurdles in plasmonics is the trade-off between electromagnetic field
confinement and the coupling efficiency with free-space light, a consequence of the large …

Radar-absorbing materials are used in stealth technologies for concealment of an object
from radar detection. Resistive and/or magnetic composite materials are used to reduce the …

In this paper we present the efficient design of functional thin-film metamaterial devices with
the effective surface conductivity approach. As an example, we demonstrate a graphene …

Owing to its excellent electrical, mechanical, thermal and optical properties, graphene has
attracted great interests since it was successfully exfoliated in 2004. Its two dimensional …

The field of metamaterials has opened landscapes of possibilities in basic science, and a
paradigm shift in the way we think about and design emergent material properties. In many …

We present a dynamically wavelength tunable plasmonically induced transparency (PIT)
planar device composed of periodically patterned graphene nanostrips for the mid-infrared …
