Undistorted Transmission of a Useful Signal by Surface Spin Waves in a Metal–Ferrite–Dielectric–Metal Structure

Abstract

A study is performed of the characteristics of a surface spin wave propagating perpendicular to the direction of a uniform magnetic field in a tangentially magnetized plane-parallel metal–ferrite–dielectric–metal structure. It is established that at certain parameters of the structure, quasilinear portions appear in the dispersion dependence of this wave which can ensure the undistorted transmission of a useful signal modulating the surface spin wave.
