Kurzfassung:
Splitting of a Tamm plasmon polariton at the interface between a metal and a nanocomposite layer conjugated with a photonic crystal (Bragg mirror) has been theoretically investigated. The splitting can be implemented when the Tamm plasmon polariton frequency approaches the resonance frequency of the nanocomposite, which consists of metallic nanoballs dispersed in a transparent matrix. The reflectance spectrum of the p -polarized waves at the normal incidence of light has been calculated. It has been established that the Tamm plasmon polariton splitting significantly depends on the concentration of nanoballs in the nanocomposite layer and its thickness. The solution of the dispersion equation derived for a sample with semi-infinite mirrors has been compared with the spectra obtained for a finite structure by the transfer matrix method.
