Abstract: The Love wave behavior in magneto-elect ro-elastic multilayered st ructures was investigated. Firstly , thegeneral mechanical displacement , elect ric potential and magnetic potential were found by solving the coupled magneto-elect ro-elastic field equations. The dispersion equation of the Love wave was then derived by the propagationmat rix method , combined with the continuity condition across the interface of the layers. Numerical result s forsandwich composites made of Ba TiO₃ and Co Fe₂O₄ were presented and discussed , including dispersion curves fordifferent stacking sequences and for different thicknesses of the middle layer.
