Nanoscale optical antennas inspired by old-school TV aerials

Abstract:
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 is scaled down to nanometer sizes and slightly modified, the result was a tiny antenna that could direct light of nanometer wavelengths. The resulting optical antenna array could help improve the design of nanoscale sensors and detectors.
