中文摘要
表面電漿波是一種侷域在金屬與介質界面之二維平面波,它對表面的結構、介質層的折射率變化有其敏感性。
本論文以嚴格耦合波分析(RCWA , Rigorous Coupled Wave Analysis)模擬金屬光柵於金屬薄膜的結構,重新了解表面電漿於週期性結構的能帶關係;藉由能帶關係觀察存在於薄膜金屬的上下界面場,以及變化光柵結構對上下界面場的影響;調制光柵表面的不對稱性對能隙之影響;此外,比較連續性的金屬光柵與一般金屬條光柵之表面電漿波特性。
Abstract
Surface plasmon resonance is a two-dimensional plane wave at interface of metal and medium. It is sensitive to the change when the change in the refractive index of the medium and the surface structure.
This study used rigorous-coupled wave analysis (RCWA) to re-examine in detail the band structure of surface plasmon resonance at a laminated metal film with metallic gratings. We observed in the presence of the upper and lower field of thin-film metal interface with the band relationship and modulate grating structure to affect the upper and lower interface field. Introducing an asymmetrical component to the grating profile intensified the band gap opening effect. Furthermore, comparison of surface plasma resonance differences in the continuity of the metal thin film above the grating and the general condition of the metal grating strips.
