Abstract：This paper investigates the propagation of SH waves in the layered plate structure consisting of a functionally graded piezoelectric layer and a piezomagnetic half space. The change of the functionally graded piezoelectric material is exponential form along x2 direction. The electrical boundary conditions is short circuit and open. Based on the dispersion equations, the numerical examples are presented to show the influence of variations of material properties, piezoelectric layer thickness and electrical boundary on the phase velocity. The resach results can provide theoretical reference for high performance acoustic devices.
