The generation of monochromatic current modulation of an intense relativistic electron beam for producing high power millimeter wave is studied theoretically. The frequency mismatch, gap electric breakdown and electromagnetic isolation of the cavities are investigated by particle simulation for various beam parameter and geometric configuration.
