Nanoimprinted Hyperlens Array for Practical Super-Resolution Imaging

Caption

a) This is a multilayered spherical hyperlens structure. Metal and dielectric thin films are deposited on a spherical shape of substrate. b) This is a transmission electron microscopy (TEM) image of the cross-section of a replicated hyperlens c & d) Tilted view for the quartz master mold and the replicated substrate e) Scanning electron microscopy (SEM) image of the sub-diffraction scale objects. f) Far-field optical image after hyperlens. The small object below diffraction limit is clearly resolved by the hyperlens.
