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 ...
Phase-change metasurfaces integrate subwavelength optical architectures with materials whose refractive index and absorption can be dynamically and reversibly altered through an external stimulus, ...
Figure 1. Concept of active metasurface with substantial broadband tunability enabled by RME. (a) Schematic of a tunable MIM resonator for dynamic light manipulation via RME. (b) Simulated magnetic ...
