Optical imaging over a plasmonic thin film with deep-subwavelength surface roughness
Subwavelength imaging has been reported for a layer of plasmonic thin film. In this paper, we investigate the enhancement of the sub-diffraction-limit imaging using subwavelength surface roughness. Full wave simulations are carried out based on Lippmann Schwinger equation with linearized scattering potentials. Progresses in experiment are also reported.
