|
摘要
提出了光栅—谐振腔复合结构.利用光学理论和粒子模拟方法研究了这种光栅—谐振腔复合结构中的史密斯—帕塞尔辐射的输出特性.结果显示:利用这种装置可以产生太赫兹波段的可调谐相干史密斯—帕塞尔辐射.这种光栅—谐振腔复合结构具有下列优点:它可以把一定发射角和任意方位角的史密斯—帕塞尔辐射同相位反馈到电子束,对电子束进行调制.
A grating-resonator composite structure was investigated. The output characteristics of Smith-Purcell radiation in this grating-resonator composite structure were studied by optical theoretic analysis and particle-in-cell simulation method. The results showthat tunable coherent Smith-Purcell radiation at Terahertz wavelengths can be generated by this novel structure. This novel grating-resonator composite structure has the following advantages: it can reflect all radiation with an emission angle and random azimuthal angles which backs onto the electron beam with same phase and cause the electrons to be modulated.
