The pattern of electron density fluctuation and electromagnetic disturbance set up by the passage of a swift ion through condensed matter. In dense media that can sustain well-defined resonance oscillations at a frequency ω0, wakes of periodic character will form behind swift charged particles having speed v. The periodicity in space, λ, the distance between troughs of the wake, is given by Eq (1).
