Harvard scientists created a light beam called an “optical rotatum” that twists and changes torque as it travels, mimicking natural spiral patterns. It offers new possibilities for controlling ...

Researchers from TU/e have transmitted data between the TU/e campus and the High Tech Campus over a 4.6 km distance using infrared light. This happened at the astonishing rate of ... Their antennas ...

The innovation of this design lies in the integration of oval-shaped patches and a tree-shaped SSPP transmission line (TL) that features a significant gradient of dispersion, enabling a high beam ...

Opaque materials can transmit light when excited by a high-intensity laser beam. This process, known as optical bleaching, ...

Why speed and secrecy usually trip over each other Today’s backbone links already move hundreds of gigabits, but they rely on ...

The printing speed can achieve about 2 cm2/minute using only a single beam laser. A 75 × 45 mm2 sulfur cathode can be printed within 20 minutes and supply power for a small screen for several ...

Also known as the Luxor Lamp, it was powered by 39 xenon lamps, each about the size of a washing machine.
