The self-consistent nonlinear theory of electron cyclotron maser based on anomalous Doppler effect

The self-consistent nonlinear equations, which describe electron cyclotron maser under the condition of anomalous Doppler effect, have been developed. By employing an initially rectilinear electron beam and a guiding static magnetic field, an efficient energy transfer between electrons and microwave can be achieved. The results suggest potential applications in designing a compact and efficient microwave generation/amplification device. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3604016]
