Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...

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 ...

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

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 ...
