摘要

我們對表面電漿波在銀表面的激發及與三維結構的交互作用進行研究，藉由雷射聚焦至以電子束顯影所製作的溝槽結構激發表面電漿，並以近場顯微鏡觀測表面電漿之傳播，我們以定量分析溝槽寬度及長度對於表面電漿之影響。我們觀測表面電漿波的波前在經過凹陷及缺陷的微米尺度孔洞時所產生的交互作用。

We report on our investigation of the excitation and interaction of surface plasmonic waves with 3D-nanostructures on silver surfaces. We excite surface plamon polaritions (SPPs) by focus 532nm laser beam on the groove that we fabricate on the silver film with electron beam lithography (EBL), and describe the propagation of the surface plasmon wave by near-field scanning optical microscopy (NSOM). We vary the length and width of the groove and measured the strength of the excited SPP waves analysis of SPPs excitation. We also characterize the propagation of SPPs wave through a dimple feature and microstructure fabricated with EBL on Ag surface.
