The dispersion and isofrequency characteristics of surface spin waves in a tangentially magnetized metal–dielectric–ferrite–dielectric–metal structure are studied. It is found that the dispersion surface of spin waves in this structure goes from the frequency axis in a wide frequency interval, in a part of which the isofrequency dependences of the waves have the form of a closed loop starting at k → 0. It is found that the dispersion surface can simultaneously have bell-shaped regions, in which the isofrequency dependences near the vertex are similar to ovals, and saddle-like regions, in which the isofrequency dependences near the saddle point are similar to hyperbolas. It is established that the range of possible orientations of the wave vector at a given frequency can be wider than the interval limited by the cutoff angles. It was found that the cross section of the dispersion surface by an angle exceeding the maximum cutoff angle is a dispersion relation with a limited interval of wavenumbers.
