  • Due to their size — each interlocking spiral nanoantenna is as wide as 1/25 the diameter of a human hair — the nanoantennas absorb energy in the infrared part of the spectrum, just outside the range of what is visible to the eye.

  • Although infrared rays create an alternating current in the nanoantenna, the frequency of the current switches back and forth ten thousand billion times a second — much too fast for electrical appliances, which operate on currents that oscillate only 60 times a second.

  • Reflecting all the gathered light in one direction means that the nanoantenna acts kind of like a mirrored magnifying glass, concentrating the light at a particular point.
