Abstract :
A theory of linear excitation of spin waves in perpendicularly magnetized double-film ferromagnetic film structures is developed. Dipole and exchange interaction as well as surface spin pinning conditions are taken into account. Expressions for spin-wave response functions and radiation resistance of a microstrip transducer for the double-film structure are derived
