摘　　要：在电磁弹性多层结构模型的基础上,通过本构方程和场方程推导出Love波在电磁弹性介质中的波动方程。利用传递矩阵方法,给出了一定边界条件下Love波在该结构中的频散方程。通过对算例进行分析,得出了Love波在电磁弹性多层结构中传播的一些特性。The Love wave behavior in magneto-electro-elastic multilayered structures was investigated. Firstly, the general mechanical displacement, electric potential and magnetic potential were found by solving the coupled magneto-electro-elastic field equations. The dispersion equation of the Love wave was then derived by the propagation matrix method, combined with the continuity condition across the interface of the layers. Numerical results for sandwich composites made of BaTiO3 and CoFe2O4 were presented and discussed, including dispersion curves for different stacking sequences and For different thicknesses of the middle layer.
