The demonstration of a Yagi–Uda nano-antenna that operates at visible wavelengths gives hope for a convenient means of directing radiation patterns from nanoscale light sources such as single ...
Researchers in Japan have built a nano-scale version of the classic antenna used to pick up TV signals in millions of homes around the world. The device, which is based on the “Yagi-Uda” antenna, ...
Standard TV antennas receive signals carried by electromagnetic waves with frequencies in the MHz range and convert them into pulses of electric currents in the connected cables. The antenna connects ...
Let there be light - and it was directional: The world's first electrically powered Yagi-Uda antenna was built at the University of Würzburg's Department of Physics. Disclaimer: AAAS and EurekAlert!
My 200m long, 2.4GHz wireless network link doesn't have a clear line-of-sight. It works well enough in good weather, but with wet or snowy or blowy foliage, it can become unusable. Since the current ...
The United States has poured ten of billions of dollars into developing fifth-generation stealth fighters such as the Lockheed Martin F-22 Raptor and F-35 Joint Strike Fighter. However, relatively ...
Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...
