a Schematic of a super-resolution imaging using cylindrical hyperlens [92]. b Experimental demonstration of the hyperlens. Two 35 nm lines are separated by 150 nm, and the wavelength of the incident light is 365 nm. From left to right, SEM image of the object, image with the hyperlens, and image without the hyperlens, respectively [92]. c Average intensity of the cross section of the line image shown in (b). Red and green indicate average intensity with and without the hyperlens, respectively. (A.U. means arbitrary units.) [92] d SEM image of the cross-sectional view of spherical hyperlens. (Scale bar indicates 500 nm) [94]. e SEM image of an object. f Magnified image obtained by using spherical hyperlens. g Red line shows average intensity of the cross section of the obtained image shown in (f). (All scale bars indicate 500 nm) [94]
