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

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

In the wake of intense research on metamaterials the two-dimensional analogue, known as
metasurfaces, has attracted progressively increasing attention in recent years due to the …

Plasmonic metasurfaces, which can be considered as the two-dimensional analog of metal-
based metamaterials, have attracted progressively increasing attention in recent years …

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 …

Vectorial optical fields (VOFs) exhibiting arbitrarily designed wavefronts and polarization
distributions are highly desired in photonics. However, current methods to generate them …

We demonstrate optically thin quarter-wave plates built with metasurfaces that generate high-
quality circularly polarized light over a broad wavelength range for arbitrary orientation of the …

We design, fabricate, and experimentally demonstrate an ultrathin, broadband half-wave
plate in the near-infrared range using a plasmonic metasurface. The simulated results show …

We demonstrate that metal–insulator–metal configurations, with the top metal layer
consisting of a periodic arrangement of differently sized nanobricks, can be designed to …

A cornerstone equation of optics–Snell's law–relates the angles of incidence and refraction
for light passing through an interface between two media. It is built on two fundamental …
