Rayleigh wave propagating in layered magneto-electro-elastic material structures

An exact approach is used to investigate Rayleigh waves in magneto-electro-elastic material structure which involves a piezomagnetic layer bonded to a semi-infinite homogeneous piezoelectric substrate. The piezomagneticity and piezoelectricity are both polarized in z-axis direction. The analytical solution of dispersion relations is obtained and the results are presented.
