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

Phase-change materials (PCMs) and compounds enable a combination of features for
implementing advanced and multifunctional nanophotonic applications. Possessing …

The development of flat, compact beam‐steering devices with no bulky moving parts is
opening up a new route to a variety of exciting applications, such as LIDAR scanning …

Drawing inspiration from radio-frequency technologies, we propose a realization of nano-
scale optical dielectric resonator antennas (DRAs) functioning in their fundamental mode …

An infrared reflectarray metasurface with engineered birefringent behavior is demonstrated.
The array reradiates incoming light into two orthogonal, linearly polarized reflections. The …

Reflectarrays composed of resonant microstrip gold patches on a dielectric substrate are
demonstrated for operation at terahertz frequencies. Based on the relation between the …

PMC is at a local maximum of absolute electric field strength. An object placed close (<< λ/4)
to the surface of a PMC will therefore have a stronger interaction with electric fields than an …

Reflectarray and transmitarray antennas have been widely used in radar detection systems
and satellite communications. Simultaneous realization of reflection and transmission of …
