Abstract :
A theory is developed for the normal mode spin-wave spectrum in the tangentially magnetized layered structure metal-dielectric-ferrite-dielectric-ferrite-dielectric-metal. Dipole and exchange interactions are taken into account. An arbitrary in-plane orientation of the external bias magnetic field with respect to the direction of spin-wave propagation is assumed. Effects of metal screen positions on the spin-wave spectrum are discussed
