Communication: The possibility of controlling structures at the light-wave- length scale would be of great consequence for near-field optical applications, such as microscopy and photolithography. These authors have created an artificial 2D crystal structure in a surrounding silver-metal film with which they demonstrate control and enhancement of the light from a single subwavelength aperture, showing a way around the Bethe limit for the transmission through a single hole. In addition the transmission can be tuned to a given wavelength through the proper design of the 2D lattice.
