Abstract
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.
