Understanding diffraction and dispersion is key to optical science, influencing technologies like spectroscopy, fiber optics, ...

In quantum mechanics, particles such as electrons act like waves and can even interfere with themselves—a striking and counterintuitive feature that defies our classical view of reality. We know this ...

A nanoscale optical device has been developed that allows independent control over the intensity and phase of light. By ...

Researchers combined OLEDs with metasurfaces to project holograms. The method enables simpler, cheaper, and smaller displays.

AST SpaceMobile plans to use the spectrum in a limited capacity. Still, it faces fierce pushback from amateur radio groups, some of which claim interference is already happening. Facing thousands of ...
