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

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 ...

Nonlinear metasurfaces are ultrathin assemblies of engineered nano-elements that combine material nonlinearity with resonant photonic design to achieve efficient frequency conversion and wavefront ...
