Abstract
This paper considers the dynamic coupled problem of harmonic oscillations of a layered inhomogeneous 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 for the medium is constructed. Dispersion curves and phase velocities for different boundary conditions and materials are obtained.
