本文给出了周期性结构金属薄膜中表面等离子体激元模隧道耦合光透射和反射的解析计算。相邻介质的影响进行了研究，在对称和非对称配置。在不同的制度，相应的双共振和单共振隧穿的透射谱进行了分析。与薄膜的表面极化激元Bloch模式相关的电磁场配置已经推导出，该电磁场配置允许直接估计反射光和透射光的远场和近场分布。解析计算的光谱与数值模拟以及现有的实验数据吻合良好。该理论提供了一个周期性结构的金属薄膜的光学特性与地形变化和/或介电常数调制的描述。
Analytical calculations of light transmission through and reflection from periodically structured metal films due to tunnel coupling of surface plasmon polariton modes are presented. The influence of the adjacent media has been studied in both symmetric and asymmetric configurations. The transmission spectra have been analyzed in different regimes corresponding to double-resonant and single-resonant tunneling. The electromagnetic field configuration related to the surface polariton Bloch modes of the film has been derived that allows direct estimation of far- and near-field distributions of the reflected and transmitted light. The analytically calculated spectra are in a good agreement with numerical modeling as well as available experimental data. The theory provides a description of optical properties of periodically structured metal films with topography variations and/or dielectric constant modulation.
