Being able to see light and detect radiation is of utmost importance at any frequency. While this challenge has been solved ...

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 ...

A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2025.240024, discusses generation of terahertz complex vector light fields on a metasurface driven by surface waves. With the rapid ...

A programmable metasurface stamps temporal codes onto ambient radio waves, enabling passive radar to detect and track drones ...
