摘要

本文提出和设计了一种X波段大直径同轴相对论返波管，用时域有限差分法数值计算了器件慢波结构中TW模式的色散关系，耦合阻抗．运用粒子模拟程序仿真了器件中注波互作用的非线性物理过程，预见出器件输出功率、效率、工作频率，并对器件功率与慢波结构尺寸，电子注束流参数，引导磁场强度之关系进行了优化分析

Abstract

An X-band large diameter coaxial relativistic backward wave aseillator （CRBWO） was prasented and designed in the paper. The complete dispersion relation and coupling impedance of TMon mode in the coaxial corrugated cylindrical waveguide used in the CRBWO were analyzed and calculated by FDTD method. An electromannetic particle-in-cell codeis being used to investigate the nonlinear beam wave interaction and perfonnance optimization issues of the device. The simulation results show that the CRBWO can generate GW level microwve power at X-band frequency very efficiently.
