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.

Traditionally, active metasurface researches have primarily focused on changing the dielectric constant and permeability of the substrate, which frequently results in resonance effect and ohmic loss.

Researchers have developed a compact quantum detector that makes terahertz radiation much easier to detect. A specially designed metasurface funnels incoming energy into tiny active regions, greatly ...
