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 ...
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 ...
Antennas receive and transmit electromagnetic waves, delivering information to our radios, televisions, cellphones and more. Researchers in the McKelvey School of Engineering at Washington University ...
(Nanowerk Spotlight) Textile engineering has long been a cornerstone of human innovation, from ancient weaving techniques to modern fabric production. However, the integration of textiles with ...
Imagine manipulating light with ultra-thin, flat sheets instead of bulky lenses and mirrors. That's the promise of metasurfaces, a nanostructure technology that can twist and bend light in ways never ...
