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.

In a paper published July 24 in the journal Nature Nanotechnology, a team of Caltech engineers reports building a metasurface patterned with miniscule tunable antennas capable of reflecting an ...

Using quantum effects in a 2D material, researchers created a tunable metasurface that toggles between reflecting and absorbing red light at room temperature. (Nanowerk News) Controlling light is an ...

Many cutting-edge technologies, ranging from augmented reality (AR) and virtual reality (VR) to LiDAR (light detection and ranging) systems, rely on components that enable the precise control of light ...
