Superoscillation
Encyclopedia
Superoscillation is a phenomenon in which a signal which is globally band-limited can contain local segments that oscillate faster than its fastest Fourier components. The idea is originally attributed to Yakir Aharonov
, and has been made more popularly known through the work of Michael Berry, who also notes that a similar result was known to Ingrid Daubechies
Such waveforms are being considered as a possible practical tool for optical engineering applications.
