Magnetophonon polaritons in the superlattices composed of alternating antiferromagnetic and ion-crystal components are investigated with the transfer matrix method. Numerical simulations based on FeF2/TlBr superlattices show that there are four different bulk polariton bands, with negative refraction and positive refraction. Many surface polariton modes with various features arise around the bulk bands with negative refraction.
