Plasmon polaritons of the TE and TM types in a metal film bordering a superlattice II. analysis of the existence of plasmon polaritons

详细

The maximum number of TE and TM polarised surface plasmon polaritons in the forbidden zone of the Bloch spectrum of electromagnetic waves in a periodic superlattice is established in structures containing a metal film between a homogeneous medium and a periodic superlattice or between two superlattices. It is demonstrated that the determining factor in the maximum number of such waves is the type of frequency dependence of the superlattice impedance. Moreover, the maximum number of surface plasmon polaritons is contingent upon the structural type and polarization of the wave.
