摘要

本文从理论上研究了两种材料交变层形成的半无限周期超晶格金属膜中TE和tm极化表面等离子体激元的极化现象。结果表明，在一定情况下，该双层超晶格的阻抗的频率依赖性只能是三种可能依赖性中的两种。计算了含有石英层和氧化钛层的双层超晶格的各种组合组成的银膜中ТE-和tm极化表面等离子激元的色散曲线。计算结果与表面等离子激元极化子最大数目的一般理论结论进行了比较。分析了电磁波在薄膜中的吸收对表面等离激元极化子特性的影响。

Plasmon Polaritons of the TE and TM Types in a Metal Film Bordering a Superlattice. III: Plasmon Polaritons in Bilayer Superlattices

The TE- and TM-polarized surface plasmon polaritons in a metal film contacting a semi-infinite periodic superlattice formed by alternating layers of two materials have been theoretically investigated. It is shown that, in a certain case, the frequency dependence of the impedances of this bilayer superlattice can be of only two types out of three possible types of dependences. The dispersion curves of ТE- and TM-polarized surface plasmon polaritons in a silver film have been calculated for a number of structures consisting of various combinations of bilayer superlattices containing quartz and titanium oxide layers. The calculation results are compared with the conclusions of the general theory on the maximum number of surface plasmon polaritons. The effect of the absorption of electromagnetic waves in the film on the characteristics of surface plasmon polaritons is analyzed.
