Smallest Nanoantennas for High-speed Data Networks
Nano dipole antennas under the microscope: The colors reflect the different trans-mission frequencies. (Photo by: LTI)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 transmission. So far, however, ma
