Today's computers reach their physical limits when it comes to speed. Semiconductor components usually operate at a maximum usable frequency of a few gigahertz—which corresponds to several billion ...

Scientists have developed a new type of "virtual" metasurface—capable of controlling light in ways traditional lenses and optics can't—which they say is superior to the current approach, which relies ...

Numerical examples for explaining the basic procedure for computational light control. (a) Single-lens optical imaging system with three distributed apertures. (b) Phase tilt is added to the small ...

Physicists present a nanometer-sized light antenna with electrically modulated surface properties -- a breakthrough that could pave the way for faster computer chips. Physicists from Würzburg present ...
