Over the past few decades, engineers have developed various devices that can create holograms, three-dimensional (3D) or ...

Holography—the science of recording and reconstructing light fields—has long been central to imaging, data storage, and encryption. Traditional holographic systems, however, rely on bulky optical ...

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.

Metasurface holography harnesses arrays of subwavelength scatterers to impart precise phase, amplitude and polarization control to incident light, enabling ultra-thin holographic elements with ...

(Nanowerk News) Metasurface technology is an advanced optical technology that is thinner, lighter, and capable of precisely controlling light through nanometer-sized artificial structures compared to ...

Metasurfaces, as open optical systems, are widely regarded as ideal platforms for creating and exploiting topological exceptional points (EPs) due to their outstanding light-field manipulation ...
