The phenomenon of resonant energization of a relativistic quantum particle,moving in unison with an intense ElectroMagnetic Wave, is demonstrated in asemiclassical calculation. The wave nature of the quantum particle is ofessence because the resonant process originates in wave-waveinteraction-between the classical EM wave, and the quantum wave associated withthe particle. When the energy /momentum of the quantum wave satisfy theresonance condition (the effective phase speeds of the two waves are equal),the particle, drawing energy directly from the intense EM field, could acquireextremely high energies Such a direct resonant energy transfer from intenseElectromagnetic waves will constitute a hitherto unexploited mechanism thatcould power the most energetic of cosmic rays. Some predictions of the theorywill, hopefully, be tested in the laboratory Laser experiments.
