Metasurfaces are planar, subwavelength‐structured interfaces that impart tailored phase, amplitude or polarisation changes to incident terahertz radiation. By engineering the arrangement and geometry ...

Tailored profiles: The working principle of the new metalaser. The designed geometric phase profile is introduced to the metasurface by rotating the hole in each silicon nitride nanodisk. Then 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 ...

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

(a) Schematic of non-local mode selection by metasurface-integrated quantum analog operation. F^1, F^2, F^3, and F^4 are the differential operators. The green area has been designed to construct ...
