摘要


開口式共振腔可以有效率地取出電子束所產生的電磁場,所以常被用於磁旋管和磁旋調速管,但其沒有明顯的邊界,大部分的情況下都沒有解析解,我們僅能透過數值模擬的方式來深入瞭解它的物理性質。 本文會先從基本的理論模型及邊界條件出發,概略性介紹數值運算所使用到的演算法,接著我們想探討當圓柱型結構加上不匹配負載,負載大小以及腔體半徑改變所產生的差異,以瞭解更多不匹配負載對於開口式共振腔的影響。

並列摘要


The EM field of electron beam can be efficiently extracted by open cavities. Therefore, open cavities are commonly used in gyrotrons and gyroklystron. Often, we don’t have the analytic solution of it. We dive deep to interpret its physical property by numerical simulation. This article begins with basis theorem and boundary conditions. Then, we will go through the algorithm used in our numerical computation. We would like to investigate the effect caused by the mismatched load attached to the open cavity. So we can learn more about the property of open cavities with mismatched load.
