Abstract :
The wake field generated by a moving charge in the vicinity of a non-magnetic material is examined in terms of the decelerating reaction force. Two main cases are investigated — the Cherenkov and Ohm effects. In the first case we examine the force which results from the Cherenkov radiation emitted as the charge moves in the vicinity of a lossless dielectric medium; in the second — the decelerating force is a direct result of power dissipated by excited currents on the surrounding lossy wall. In both cases, for highly relativistic particles the force is independent of the particleʹs energy.
