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.

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 ...

Optical metasurfaces to perform optical analog spatial differentiation operations and image edge detection processing is a currently hot topic. However, some metasurface differentiators are limited by ...

This video presents a study in which researchers developed a passive metasurface that uses a time-varying interlocking mechanism with metal-oxide-semiconductor field-effect transistors to selectively ...

A new metasurface design greatly improves light emission in atomically thin materials, offering a path to low-power, flexible, high-brightness display technologies. But there’s a problem: even though ...

The iridescent blue of butterfly wings has inspired researchers to find a solution to a challenge previously considered insurmountable - dynamically tuning advanced optical processes at visible ...
