dc.description.abstract | 在本論文中,我們將電磁波打入滑軌式波導金屬微米環結構, 研究如何能使電磁波透過滑軌式彎曲波導,在金屬微米環上激發出最多的表面電漿。
我們提出一種分析方法,能夠得知表面電漿有效的激發條件為何,進而節省製成成本、省去實驗上嘗試錯誤的時間。我們以保角映射法結合亥姆霍茲方程式,計算在不同激發條件下,電磁波在彎曲波導內的等效入射角,得到不同模態電磁波之等效入射角與波導寬關係圖。並利用色散曲線圖去預測表面電漿的共振角。當等效入射角等於表面電漿共振角時,則能在金屬微米環上激發出最多的表面電漿。
對於理論分析結果的準確性,我們使用COMSOL數值分析軟體來做結構模擬,驗證出理論分析的結果具有相當的準確性。本論文的滑軌型波導表面電漿偏極子金微米環結構,其表面電漿共振角在色散曲線的預測下為17.1度,而在我們所提出的分析方法中為17.2度,誤差為0.5%,可有效預測並節省製成上的嘗試時間。 | zh_TW |
dc.description.abstract | In this paper, we study the condition to excite the surface plasmon in the pulley-type metallic microring structure. Helmholtz equation is applied to determine the equivalent incidence angle of the curved waveguide with different-order in the TM modes by the conformal transformation method. The surface plasmon excitation angle is confirmed by the finite-element method. The pulley-type metallic microring structure is analyzed for different structures to obtain stronger surface plasmon excitation. | en_US |
