A wall-mounted metasurface powered by a large language model interprets voice commands and uses ordinary WiFi signals to ...

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

a, structure of LED based on PeNCs without and with passivation. Schematic illustrates that CP could passivate defects, in which the defects may trap carriers (e.g. holes, electrons), decrease exciton ...

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.

a. A typical scenario in which complex targets with different spectral and polarization information in low-illumination background need to be distinguished by airborne or spaceborne payloads. b. In ...
