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 ...
Antennas have played a vital role in the field of communications. Wireless transmission and reception of signals have greatly impacted our everyday lives. The Yagi-Uda antenna or Yagi Antenna is one ...
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 ...
A paper published in Nature this week details how researchers have taken a common antenna design and replicated it on the the nanoscale level. When a regular TV aerial that handles radio frequencies ...
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!
This is a nanoscale source of "collimated" light, whose rays are nearly parallel. A quantum dot drives an optical Yagi-Uda antenna giving a highly directed beam of single photons. This image relates ...
BEDFORD, Mass.--(BUSINESS WIRE)--Fractal Antenna Systems, Inc. (FRACTAL) today announced upcoming issuance of a fundamental patent on unidirectional antennas, that replace existing applications with ...
We’ve heard reports that internet connectivity in Australia can be an iffy proposition, and [deandob] seems to back that up. At the limit of a decent DSL connection and on the fringe of LTE, [deandob] ...
