Power/Performance Bits: Feb. 4

By Jesse Allen - 04 Feb, 2020 - Comments: 0

Infrared nanoantenna Researchers at the University of Würzburg built a nanoantenna capable of generating directed infrared light. The Yagi-Uda antenna is the smallest of its type yet created. "Basically, it works in the same way as its big brothers for radio waves ," said René Kullock, a member of the nano-optics team at Würzburg. An AC voltage is applied that causes electrons in the met... » read more
