Abstract

We investigate the propagation of surface plasmon polaritons (SPPs) at the boundary of metamaterial and topolological insulators. Instance of Bi2Se3 and metamaterial boundaries is investigated. The topological insulators under consideration are three dimensional topological insulators of the second generation. Dispersion relations, absorption characteristics and propagation lengths of SPPs are calculated. The key parameters making a dramatic impact on propagation lengths are acknowledged and mechanisms for engineering dispersion properties are suggested.
