Abstract
A method for the controlled generation and amplification of electromagnetic waves and systems utilizing these waves are disclosed. An incident electromagnetic wave of a given frequency stimulates a beam of moving charged particles to radiate in a polarizable medium. The resulting electromagnetic radiation is emitted intensively in highly directional shock waves of narrow-frequency bands about controllable frequencies that are in general substantially different from that of the incident wave. The energy of the radiation so produced can be substantially greater than that of the incident wave. The additional energy is supplied by the moving chaged-particle beam. The method leads to new and novel frequency-transferred wave sources and radiation amplifiers applicable to communication systems, to more efficient laser pumping systems, and to new laser systems, called frequency transducers. These frequency transducers are high-gain sources with controlled frequencies that are highly shifted relative to the initiating frequency.
