Abstract	This paper has studied the frequency band characteristics of the piezoelectric/piezomagnetic layered periodic composites. Both piezoelectric and piezomagnetic materials are assumed to be transversely isotropic. The displacement transfer coefficients of all the scattered waves are calculated by the transfer matrix and the stiffness matrix methods. Numerically calculated results show that the band structures are described consistently by the dispersion curves and the frequency responses of the transmitted waves. The most energy is carried by the transmitted waves which are of the same mode as the incident wave when the frequencies are at the passbands. However, the displacement transfer coefficients of quasi-transverse (QSV) or quasi-longitudinal (QP) waves arising from wave mode conversion may be very large at some particular frequencies in some passbands. Compared to the coupled transmitted magnetoacoustic (MA) and electroacoustic (EA) waves, the transfer coefficients of electric potential (EP) and magnetic potential (MP) waves are a little bigger.
