Book excerpt: Superoscillation is the phenomenon where a wave locally oscillates faster than its largest frequency component. While previous proof of concept experiments demonstrated super-resolution imaging by using superoscillation to generate a waveform with a main beam narrower than the diffraction limit, such a superoscillation waveform is worse than conventional methods when imaging complex objects. In this work, a new kind of superoscillation, where the main beam is around the same width as the diffraction limit, but the side lobes are significantly lower, are studied. Super-resolved images of complex objects are obtained using this new superoscillation waveform.
