| 摘 要： | 对双光栅绕射辐射器件谐振系统的Q值特性进行了分析,研究了谐振系统结构参数对Q值的影响及其优化措施。结果表明,双光栅绕射辐射器件谐振结构的Q值受矩形槽宽度和球面开放腔长度的影响最为明显。与奥罗管相比,双光栅绕射辐射器件中光栅的引入对Q值的影响要小得多,且光栅齿宽和齿深的增加都会导致谐振系统Q值降低。

| Abstract: | The characteristics of Q factor in dual-grating diffraction radiation device were studied, and the influence of structural parameters of resonant cavity on Q factor was discussed. The results show that the Q factor in cavity resonator is significantly affected by the width of the rectangular cavity and the length of the spherical open cavity. Compared with Orotron, the impact on Q factor of grating is much smaller in dual-grating diffraction radiation device, and the increments of both grating width and grating depth would lead to decreasing of Q factor. |
