Annotation In the given paper, the dispersion properties of surface electromagnetic waves at a plane interface between a homogeneous medium (vacuum) and a layered periodical structure, consisting of alternating layers of ferrite and a semiconductor, placed in an external magnetic field are studied. This structure is considered in the subwavelength approximation. To describe the dielectric and magnetic properties of the material under consideration, the effective medium theory has been applied. The material parameters have been described by means of effective components of the permittivity and permeability. It was found that in a certain range of frequencies and magnitudes of external magnetic fields, in such a structure the existence of surface electromagnetic waves occur, both TM and TE polarized. Due to the peculiarities of the structure under consideration it is possible to effectively control the parameters of surface waves.
