Modern redux of classic experiment illuminates nanoscience of 'plasmonics'

The science of plasmonics describes how metals can essentially transmit and manipulate light waves at length scales much smaller than their wavelengths. Now, by redoing a classic optics experiment with plasmonics, engineers have made key insights into the nature and the practical limits of this up-and-coming nanoscale information technology.
