The processes are considered of refraction and reflection of surface spin waves in inhomogeneous dielectric ferromagnetic medium. In the frameworks of the formalism of spin density in exchange mode the equation of magnetic moment dynamics and the dispersion low of spin waves are obtained. The eikonal equation and refraction indexes are obtained. The field and frequency dependencies of refraction indexes and reflection coefficients of spin waves are defined in an interface of two uniform biaxial ferromagnets with different parameters of exchange interaction, magnetic anisotropy and saturation magnetization. It is shown the possibility to use the proposed system as spinwave analogs of optical devises.
