Dispersive characteristics of SH waves propagating with an angle θ through one-dimensional elastic/piezoelectric/piezomagnetic phononic crystal are studied in this paper. Firstly, Secondary horizontal wave (SH wave) are studied in this paper. Secondly, the transfer matrix method is used to derive the dispersion equations. The solving process is as follow. The state vectors on both sides of the sub-layer in a unit cell are connected by a matrix, and those on both sides of the interface between the adjacent sub-layers are connected by an identical matrix. Thus, a matrix connecting the state vectors of both sides of the unit cell can be gotten, and the dispersion equation will be derived with the Bloch Theory. Finally, the effect of the component ratio is considered.
