Pronunciation
Noun
superoscillation (usually uncountable, plural superoscillations)
- The phenomenon by which a globally band-limited signal can contain local segments that oscillate faster than its fastest Fourier components.
- 2015, Achim Kempf, Angus Prain, “Driving Quantum Systems with Superoscillations”, in arXiv:
- We conclude that, either superoscillations really can beat the bandlimit and achieve superresolution (`kinematic superresolution') or the superoscillating high frequency is absorbed and we gain dynamical access to the physics of high frequency processes with low frequency signals (`dynamical superresolution')..
