Abstract. Localized magnetic polaritons are investigated in the systems consisting of

two magnetic superlattices, coupled by a ferromagnetic contact layer. The general dis-

persion relation for localized magnetic polaritons are derived in the framework of the

electromagnetic wave theory in the Voigt geometry by the `transfer' matrix method. The

numerical calculations were carried out for different parameters of the superlattices and

contact layer and then discussed.

 

Keywords. Magnetic polariton; magnetic superlattice; dispersion relation.
