dc.description.abstract | 在這篇論文中,我們利用”變換光學”設計在二維平面上圓柱型電磁斗篷的材料參數,並且可以利用色散關係不變的方式簡化之,以增加實驗的可行性。我們分析藉由不同的新舊座標之間的轉換關係式設計的斗篷,並模擬電磁波在材料中的傳播情形。我們期望避免材料參數奇異值的出現並減低整體對外界造成的散射量,從討論中可以知道座標轉換函數的選擇會對材料參數及屏蔽效果的影響甚大,利用這些討論提供一個不同的轉換方程式的設計,並以定性與定量的方式驗證並討論不同轉換關係的簡化斗篷之特性及其屏蔽物體的效果。 | zh_TW |
dc.description.abstract | In this study, we, according to transformation optics, derive the material parameters of cylindrical electromagnetic cloak in two dimensional space, and then we further simplify the parameters according to the inalterability of dispersion relation to make the experiment possible to implement. The analysis of the electromagnetic cloak in this study is based on coordinate transformation functions and the propagation characteristics of electromagnetic waves. Our primary goal is to reduce scattering, and to prevent the occurrence of singular values of material parameters. We discover the fact that the material parameters and the cloaking performance will be strongly influenced by the way of selecting coordinate transformation functions. According to the fact, we devise a new transformation equation, which has been verified based on several comparisons between the scattering characteristics and the degree of scattering. We then discuss the relations between the characteristic of simplified cloak in different transformation relations and the electromagnetic cloak's performance on cloaking subjects. | en |
