Generation of superoscillatory waves

Caption

Generation of optical superoscillatory waves without side lobes along a dimension. (a) Electron micrograph of the sample used for experiment. (b) Experiment measurement for free-space propagation of the superoscillatory waves. (c) Experimental intensity distribution of the superoscillating focusing wave in the transverse plane at z = 6.2 μm. (d) Intensity profiles along y axis (x = 0) of (c). The full width at half maximum was indicated experimentally in the panel. The blue curve represents the experiment while the red curve denotes the simulation.
