New research explores silicon nanorods in metasurfaces for polarization holographic encryption, addressing image recovery and ...

Figure 1. Schematic diagram of the racemic metasurface. (a) Arbitrary polarization-wavefront conversion. (b) Racemic "super-units". Chirality is one of the fundamental phenomena widely present in ...

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 ...
