Metasurfaces are ultrathin metamaterials consisting of planar electromagnetic (EM)
microstructures (eg, meta-atoms) with pre-determined EM responses arranged in specific …

Metamaterials, artificial composite structures with exotic material properties, have emerged
as a new frontier of science involving physics, material science, engineering and chemistry …

Becoming invisible at will has fascinated humanity for centuries and in the past decade it
has attracted a great deal of attention owing to the advent of metamaterials. However, state …

Electromagnetic metasurface cloaks provide an alternative paradigm toward rendering
arbitrarily shaped scatterers invisible. Most transformation-optics (TO) cloaks intrinsically …

Benefitting from the flexibility in engineering their optical response, metamaterials have
been used to achieve control over the propagation of light to an unprecedented level …

Surface topography and refractive index profile dictate the deterministic functionality of a
lens. The polarity of most lenses reported so far, that is, either positive (convex) or negative …

Balancing complexity and simplicity has played an important role in the development of
many fields in science and engineering. One of the well-known and powerful examples of …

We report the first experimental realization of a three-dimensional thermal cloak shielding an
air bubble in a bulk metal without disturbing the external conductive thermal flux. The cloak …

We discuss here the use of a graphene monolayer to realize the concept of “cloaking by a
surface”, proposing the thinnest possible mantle cloak with operation in the far-infrared and …

Invisibility cloaks, a class of attractive devices that can hide objects from external observers,
have become practical reality owing to the advent of metamaterials. In previous cloaking …
