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.

On the other hand, to understand the fine details of how THz interacts with matter, capturing what happens very close to the device’s surface—the “near-field phenomena”—is essential. Existing THz ...

A project at Queen Mary University of London has developed a novel biosensor using metasurfaces to detect terahertz radiation, designed to spot the onset of skin cancer. Published in IEEE Transactions ...

The design strategy for terahertz metasurfaces capable of achieving spin-selective functionality through complex-amplitude modulation is systematically categorized into four distinct parametric ...

(Nanowerk News) The quality factor (Q) is a critical parameter that characterizes the strength of light-matter interactions. Cavities with higher quality factors have the ability to efficiently ...

(Nanowerk News) The future of wireless communications is set to take a giant leap with the advent of sixth-generation (6G) wireless technology. A research team at City University of Hong Kong (CityU) ...
