The exact dispersion equation of electromagnetic modes propagating in structures that include tangentially magnetized ferrite film with surfaces bordered on media with different permittivity is derived. In the low­wavenumber range the comparison of the theoretical calculation with the experimental measurement of dispersion of magnetostatic surface waves propagating in the layered structures of such  types as dielectric­tangentially magnetized ferrite film of yttrium iron garnet–gadolinium gallium garnet is made. It has been found that in the low­wavenumber range the magnetostatic surface waves correspond to electromagnetic surface modes. The behavior of dispersion characteristics of electromagnetic surface modes depending on the thickness of ferrite film is analyzed. It has been shown that in structures investigated at given values of bias field and saturation magnetization of ferrite film the bottom wavenumber value and the lower frequency range limit of electromagnetic surface modes are determined by the ferrite film thickness and by the permittivity of media in structure.
