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 …

This paper is a critical review of metasurfaces, which are planar metamaterials.
Metamaterials offer bespoke electromagnetic applications and novel properties which are …

Metasurfaces enable a new paradigm to control electromagnetic waves by manipulating
subwavelength artificial structures within just a fraction of wavelength. Despite the rapid …

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 …

Metasurfaces are nanostructured devices composed of arrays of subwavelength scatterers
(or meta-atoms) that manipulate the wavefront, polarization, or intensity of light. Like most …

Traditionally,“metamaterials” have been described by effective medium parameters due to
the subwavelength nature of unit particles. The continuous nature of medium parameters …

In this paper, we propose a new metasurface that is able to reflect a known incoming
electromagnetic wave into an arbitrary direction, with perfect power efficiency. This …

Metasurfaces, composed of 2-D planar arrays of sub-wavelength metallic or dielectric
scatterers, have provided unprecedented freedoms in manipulating electromagnetic (EM) …

We review the current trends in the design of Huygens' metasurfaces (HMSs), which are
planar arrays of balanced electric and magnetic polarizable particles (meta-atoms) of …

We introduce a paradigm for accurate design of metasurfaces for intricate beam
manipulation, implementing functionalities previously considered impossible to achieve with …
