Description/Abstract
Here for the first time we demonstrate experimentally and theoretically that the Talbot effect on a quasi-periodic array of nano-holes may be used to achieve sub-wavelength field localizations and well-isolated 'hot spots' of high electromagnetic energy concentration.Here we report on how a quasi-periodic array of holes creates sub-wavelength localizations of light without evanescent waves and how the fields created by such diffraction fall into the class of super-oscillating fields [1]. This effect offers a new way to achieve sub-wavelength imaging in the far field.
