A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

Electromagnetic (EM) wave front modulation has important significance in both scientific researches and industrial applications. However, conventional dielectric materials have limited choices of ...

To overcome the lack of wavelength-selective extraction in existing on-chip metasurfaces, Chinese scientists developed a novel approach by leveraging a nonlocal on-chip design based on symmetry-broken ...

Metasurface converts Gaussian beams to uniform light via polarization encoding, boosting NMR co-magnetometer sensitivity 23% for compact quantum sensors.

It has long been considered common sense that a single device performs only one function. Just as tuning a radio to a ...
