Since the Generalized Snell's Law (GSL) was proposed, planar metasurfaces have achieved remarkable progress in optical and electromagnetic wavefront manipulation by leveraging phase gradients. The ...

A research team has demonstrated the first nonlinear metasurface with engineered nonlocality, that simultaneously delivers high‑Q resonance enhancement and pixel‑level control of the wavefront of ...

New metasurfaces with nanoantennas could replace lenses and enhance AR, VR, LiDAR, and more by precisely controlling light. (Nanowerk News) Antennas receive and transmit electromagnetic waves, ...

Layered metasurfaces trained as optical neural networks enable multifunctional holograms and security features, integrating neural computation principles with nanostructured optics to create a ...
