中文摘要：
采用传递矩阵方法,研究了横波（SV波）垂直入射时压电/（弹性/压磁）和（压电/弹性）/压磁两种Fi-bonacci准周期结构的频带特性,通过计算局部化因子和位移透射系数,数值揭示了此两种Fibonacci准周期结构频带特性的差异以及与相应理想周期结构频带特性的不同,而且表明（压电/弹性）/压磁Fibonacci准周期结构的频带特性与纯弹性材料Fibonacci准周期结构的频带特性是相似的.
英文摘要：
Band gaps for the two kinds of magneto-electro-elastic quasi periodic structures with Fi bonacci sequence,one is the piezoelectric/（elastic/piezomagnetic） and the other is the （piezoelectric/elas tic）/piezomagnetic, are studied by the transfer matrix methods. The normal incidence case for the shear waves （SV waves） is considered. The localization factors and displacement transmitted coefficients are com- puted and their band gaps are compared with the corresponding perfect periodic structures. The results show that the band gaps of the two structures are quite different. The band gaps for the （piezoelectric/elas tic）/piezomagnetic quasi-periodic structures are indeed similar to those of the pure elastic structures with Fibonacci sequence.
