Superoscillation refers to a phenomenon where a function, such as a wave or signal, oscillates at frequencies higher than its highest Fourier component. In simpler terms, it allows a signal to display rapid oscillations that exceed the fastest oscillation of the components that make it up. This can occur in various fields, including optics, signal processing, and quantum mechanics.
