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.
The transfer matrix method is used to study the frequency characteristics of the piezo / (elastic / piezomagnetic) and (piezoelectric / elastic) / piezomagnetic two-period Fi-bonacci quasi-periodic structures at normal incidence of transverse wave (SV wave) Factor and displacement transmissivity, the values reveal the difference between the two Fibonacci quasi-periodic structure band characteristics and the band characteristics corresponding to the ideal ideal periodic structure, and show that the band characteristics of the (piezoelectric / elastic) / piezomagnetic Fibonacci quasi-periodic structure and The band characteristics of Fibonacci quasi-periodic structures of pure elastomers are similar.
