Abstract:

The system of an ideal metal or superconductor - dielectric plate - vacuum or unpolarizable substance is considered in presence of the constant electric field directed normal to the plane of the plate. Dispersion relations for surface phonon polaritons of this system are derived and analyzed. These polaritons are induced by a dynamical magnetoelectric effect. It has been shown that in the case, when the plate thickness essentially exceeds the penetration depth of the surface polaritons, the approximation of a half-infinite bulk insulator satisfactory describes the polariton spectrum and the switching over effect is possible for a magnetoelectric wave the variation of the electric field on the opposite one leads to switching on or switching off of the corresponding frequency branches. The dependence of the spectrum of surface phonon polaritons from the plate thickness is calculated numerically. The corresponding criterion of an existence of magnetoelectric waves in the dielectric plate has been found.
