Abstract :
We have presented experimental evidence of free-space imaging beyond the diffraction limit at 2.4 GHz using a Veselago-Pendry superlens based on a multilayer implementation of the NRI-TL metamaterial, which reveals focusing of a single source to a minimum peak-to-null beamwidth of less than one-sixth of a wavelength.
