Controlling electromagnetic waves and information simultaneously by information
metasurfaces is of central importance in modern society. Intelligent metasurfaces are smart …

Metamaterials are composed of periodic subwavelength metal/dielectric structures that
resonantly couple to the electric and/or magnetic components of the incident …

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 …

Surfaces covered by ultrathin plasmonic structures—so-called metasurfaces,,,—have
recently been shown to be capable of completely controlling the phase of light, representing …

Metasurfaces are planar structures that locally modify the polarization, phase and amplitude
of light in reflection or transmission, thus enabling lithographically patterned flat optical …

The ideal material for nanophotonic applications will have a large refractive index at optical
frequencies, respond to both the electric and magnetic fields of light, support large optical …

Optical metalenses—two-dimensional arrays of submicrometre scatterers that collectively
focus light—have experienced growing research interest in recent years as they can realize …

Control over the dispersion of the refractive index is essential to the performance of most
modern optical systems. These range from laboratory microscopes to optical fibres and even …

Subwavelength resolution imaging requires high numerical aperture (NA) lenses, which are
bulky and expensive. Metasurfaces allow the miniaturization of conventional refractive optics …

Background Metamaterials (MMs) are smartly engineered structures with rationally
designed, nanostructured building blocks that allow us to build devices with distinct …
