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 ...

The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging.

Researchers have demonstrated the world's first metasurface laser that produces "super-chiral light": light with ultra-high angular momentum. The light from this laser can be used as a type of ...

(Nanowerk Spotlight) Controlling how electromagnetic waves behave as they move through space is essential for technologies like wireless communication, radar, and remote sensing. Engineers have ...

In the realm of active 3D imaging, the light detection and ranging (LiDAR) technology plays a pivotal role, offering direct depth acquisition and robust resistance to environmental noises. LiDAR ...
