摘要
在微波技术向太赫兹波段推进过程中, 人们关注的核心问题是器件的频率、效率或功率问题。文章从Maxwell方程出发, 对两腔微波振荡器的束流动力学与束-波转换效率进行了讨论。在经典力学框架内, 把电子相位运动方程化为摆方程; 从系统的相平面特征出发, 讨论了器件的接受度和束-波转换效率。结果表明, 当相空间密度均匀分布时, 相面积越大束流越强, 功率越高; 而能散越大束-波作用越强, 转换效率越高。
Abstract
In the attempt to promote microwave technology to terahertz band, the key problems are frequency, efficiency or power of the device. Based on the Maxwell equations, the beam dynamics and beam-wave conversion efficiency were discussed for the microwave oscillator with two-cavity structure. In the framework of classical mechanics, the motion equation of electronic phase was reduced to the pendulum equation. And from the phase plane properties of the system, the acceptance and the beam-wave conversion efficiency of the device were discussed. The results show that when the phase space density is in uniform distribution, larger phase area results in stronger beam and higher power; and the greater the energy spread is, the stronger is the interaction of beam-wave and the higher is the conversion efficiency.
