周期阵列微纳结构金属薄膜的透射特性
|
摘要
选择周期阵列微纳结构金属银膜作为研究对象,用有限元方法对其透射特性进行了数值模拟。研究了孔径大小、金属膜厚度、阵列周期以及入射光的偏振状态对微纳结构透射谱线的影响。结果表明,透射谱线只对阵列周期的变化敏感。
The silver film with a periodically arrayed micro-nano structure is chosen as the research object and its transmission characteristics are numerically simulated with the finite element method.The effects of the aperture size,the film thickness,the array period and the polarization state of the incident light on the transmission spectra of this micro-nano structure are analyzed.The results show that the transmission spectra are only sensitive to the change of the array period.
