Abstract：Dispersion of surface wave in an electro-magneto-elastic compositons layered plate is investigated by hybrid numerical method. Material properties, electric coefficient and magnetic coefficient are supposed to vary linearly in the thickness direction. The electro-magneto-elastic compositons layered plate is first devided into strip elements. the governing equations of an element are obtained, and then the governing equations of the elements are assembled into the total equations. The dispersion of waves can be obtained by solving eigenvalue equation of the system. Effect of electric and magneto field on the dispersion of waves is investigated
