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. 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. German scientists have now succeeded for the first time in specifically and reproducibly manufacturing smallest optical nanoantennas from gold.
