摘要: | 開口式共振腔的研究常運用在磁旋管、磁旋振盪管中,與閉口式不同的是開口是共振腔有著明確的邊界條件,因此本論文運用程式做數值模擬分析來探討其不同的物理意義。 主要是從時域模型出發,推導模型的數學基礎和其邊界條件,並定義在時域模型下的品質因子。 本論文是基於先前的基礎研究下去做更深入的探討,在基礎模型中,改變開口式共振腔的物理結構,去探討不同結構下的共振頻率、品質因子、場強等結果,並結合電動力學予以解釋及驗證該特徵。 The research of the open cavity is often used in the magnetic tube and the magnetic oscillating tube. The difference between the closed cavity and the open cavity is that the resonance cavity has clear boundary conditions. Therefore, this paper uses a program to do numerical simulation analysis to explore its different physics significance. Mainly starts from the time domain model, derives the mathematical basis of the model and its boundary conditions, and defines the quality factor under the time domain model. This thesis is based on the previous basic research to do more in-depth discussion. In the basic model, the physical structure of the open cavity is changed. We derive the formula of power flow by electrodynamics and analyze the results of the resonance frequency, quality factor, field strength under different structure. Finally we give an appropriate physical explainatoin for the feature. |
