An electrodynamic model that describes the dispersion of magnetostatic surf
ace waves in ferrite/superconductor structures is suggested. On its basis,
a new approach to determining the microwave sheet resistance R-S of superco
nducting films in a magnetic field is elaborated. The values calculated (R-
S = 0.20-0.96 m Omega) agree with results obtained by the Tauber method. Fo
r YIG/YBCO structures, the controllable phase shift is about 1.5 pi when th
e depth of magnetostatic wave penetration into the YBCO film varies from 2.
