From the telescoping rabbit ears of television sets to giant dishes capable of receiving faint radio signals emanating from distant galaxies, antennas play key roles in the detection of long-wavelength electromagnetic radiation. Scientists at the National Institute of Standards and Technology (NIST) in Boulder, Colo., have now fabricated tiny antennas that effectively capture infrared radiation, thereby extending antenna technology to shorter wavelengths.
"Our work on small antennas is part of a larger effort to move microwave-like technology toward shorter wavelengths, and this work represents the shortest wavelength to which it has been pushed so far," says ...
