Superoscillation
noun ·Rare ·Advanced level
Definitions
- 1 The phenomenon by which a globally band-limited signal can contain local segments that oscillate faster than its fastest Fourier components. uncountable, usually
"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').."
