Theory and simulation of beam-wave interaction of the gyro-peniotron

Abstract

Starting from the relativistic equation of motion and the energy equation of electron, a largesignal theory, which describes the beam-wave interaction in a gyro-peniotron, is presented in this paper. The theory is valid for arbitrary TE_mn modes and arbitrary harmonics of the cyclotron frequency. Numerical simulation shows that under defined conditions an electronic efficiency of about 45% for the third cyclotron harmonic at an operation frequency of 35GHz could be obtained, While the required DC magnetic field is only 4.2kGs. This fact indicates that this device could be efficiently operated at high power level, high efficiency, high frequency and low magnetic field. Therefore, the practical applications of the gyro-device will be greatly extended and the potential for short-millimeter and submillimeter wavelength exists.
