本論文模擬一系列之奈米銀金屬結構的表面電漿子激發現象，包括銀薄膜的Groove結構、奈米銀金屬球結構，奈米銀金屬塊結構、以及利用多顆奈米銀金屬塊組成奈米銀柱結構。在前面三種模擬的部分，主要是探討改變模擬區域範圍、格網大小、奈米銀金屬球(塊)之大小，藉由這些改變，來觀察入射波波長對穿透係數或消散係數(Total Q)關係圖的變化。在奈米銀柱的部分，主要是改變奈米銀金屬塊之排列方式，觀察電磁波是如何透過表面電漿子傳遞，本研究發現，奈米銀金屬塊之間距，對表面電漿子能否在奈米銀柱裡傳遞的一個重要關鍵。

　　This essay approximates the intense reaction of Surface Plasmon Polariton(SPP) in the series of nano silver metal structure, including the silver membrane of Groove structure、the nano silver metal sphere(piece) structure, and by utilizing many nano silver metal pieces to composing the nano silver rod structure. In the 3 previous approximations that are mainly about the researches and discussions to the changes of the approximated zone, the sizes of the grids, and the sizes of the nano silver metal sphere(piece).According to the results, to observe the changes in wavelength of the incident wave in transmission coefficient or dispersion coefficient (Total Q) chart. As to the nano silver rod part, it is mainly to change the arranging order of the nano silver metal pieces, and to observe how the electromagnetic wave passes through SPP. The research has discovered that the distances in among of those nano silver metal pieces, has become the key point to determine if the SPP can be transmitted into the nano silver rod.
