Sub-Wavelength Lensing

Abstract:
Sub-wavelength lensing in flat panels of left-hand materials (LHM) has been seen in two new experiments. What this means is that a planar sheet - and not something that has to be machined into a traditional lens shape - can be used to focus light into a tight spot. The size of this spot, furthermore, is less than half the wavelength of the light being used.
