It is shown that if a charged particle moves among a large number of antennae, each of which radiates an electromagnetic wave, the energy and momentum of the particle is increased in a stochastic manner. This acceleration is a resonant process; at various points on its orbit, the particle encounters regions in which the phase of the beats between a pair of waves encounters the frame in which the particle is, on the average, at rest. The energy and momentum of a particle change in a secular manner at these points together with this phenomenon, when summed over all resonances, leads to a stochastic acceleration if the antennas are randomly located. This process may be significant in models of quasi-stellar objects and active galactic nuclei which rely upon strong electromagnetic waves as the basic energy input.
