Some features of the dynamics of ferroelectric (ferromagnetic) heterostructures

Abstract

This paper considers the dynamic coupled problem of harmonic vibrations of a layeredinhomogeneous electromagnetoelastic medium subjected to an oscillating mechanical or electrical load under various electric and magnetic field conditions specified on the surface and internal boundaries of this medium. Green’s function of the medium is constructed. Dispersion curves and phase velocities for different boundary conditions and materials are obtained.
