摘要

在本篇論文中，延續了學長的研究，在證實了漸近邊界條件(ACBCs)的應用領域可擴增至球座標系統後，開始探討縱向溝槽圓錐在不同頻率、結構錐度、溝槽寬度，封閉情況和開放情況的電磁場變化。並設計一種易於量測電磁場分布的尺寸去實作，透過比較模擬結果和量測結果後，最後證實解析場、數值場和實際量測結果有良好的對應，以更加確定漸近邊界條件能很好的模擬真實世界的情況。

In this paper, continue the research of senior’s paper. After confirming that the Asymptotic Corrugation Boundary Conditions (ACBCs) can be applied in spherical coordinate system, we begin to discuss the effects of three factors which affect the distribution of electromagnetic fields in the longitudinally corrugated cone. We consider three factors: 1. Frequency. 2. Taper of structure. 3. Width of the groove.
After the discussion is completed, we design a kind of size which is easy to measure the distribution of the electromagnetic field to imply. In the end, with the favorable similarity between the simulation results and the measurement results, we can be more certain that the ACBCs can analyze the structure in spherical coordinate system well.
