Anomalous Doppler effect observed during propagation of magnetostatic waves in ferromagnetic films and ferrite-dielectric-metal structures

The anomalous Doppler effect observed during propagation of magnetostatic backward volume waves in a free ferromagnetic film and magnetostatic surface waves in a ferrite-dielectric-metal structure is investigated. The effect is theoretically substantiated, and plots of Doppler frequency shift are constructed. The anomalous Doppler effect is qualitatively analyzed with the use of equifrequency curves.
