Even as I am getting ready to post about nanoantennas that are revolutionizing high-speed networks, there’s news of Andy Pag, the green traveller of Biotruckexpedition arrested for carrying Sat phone banned in India! To put it in a nutshell, technology can help you cross the borders but you also run the risk of losing your freedom!! We are back to square one, aren’t we!!!

Nanoantennas for high-speed data networks
More than 120 years after the discovery of the electromagnetic character of radio waves by Heinrich Hertz, wireless data transmission dominates information technology. Higher and higher radio frequencies are applied to transmit more data within shorter periods of time.

According to the Labspaces report, Some years ago, scientists found that light waves might also be used for radio transmis-sion. So far, however, manufacture of the small antennas has required an enormous expenditure. KIT scientists have now succeeded for the first time in specifically and reproducibly manufacturing smallest optical nanoantennas from gold.
