Meaning of superoscillation | Babel Free

Definitions

The phenomenon by which a globally band-limited signal can contain local segments that oscillate faster than its fastest Fourier components.

uncountable, usually

Examples

“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')..”
