Abstract: The interaction of an electromagnetic radiation with electric dipole active spin modes in a multisublattice antiferrodielectric is shown to possibly lead to anomalous (negative) spatial shift of a light beam when an electromagnetic wave is incident on the interface with an isotropic dielectric medium.

Keywords: surface polaritons, negative refraction, Goos–Hanchen shift, electric dipole active antiferrodielectric.
