Abstract

In conventional microwave tubes electron beams propagate through structures which effectively reduce the phase velocity of electromagnetic waves below the speed of light in vacuo. In such cases, an electron beam propagating parallel to the waves with a velocity close to the wave phase velocity can engage in a resonant interaction with a high intrinsic efficiency.
