摘要研究了具有磁电-机械非理想接触的压电半空间和压磁半空间界面间的剪切水平波的传播。机械缺陷、电气缺陷和磁性缺陷分别由弹簧、电容器和电感来模拟。给出了文献中未见报道的色散关系的一般表达式，并对各种极限情况进行了详细的分析。在某些极限情况下，还得到了预测界面波存在的新表达式。在其他情况下，当已报告的结果存在时，将与它们进行比较。一些物理解释是从极限情况得到的。通过数值算例说明了机械接触、电磁接触和电磁接触缺陷的影响。
Abstract We study the propagation of shear horizontal waves between the interface of piezoelectric and piezomagnetic half-spaces with a magneto-electro-mechanical imperfect contact. Mechanical, electrical and magnetical imperfections are modelled by means of a spring, a capacitor and a inductor, respectively. A general expression for the dispersion relation not reported previously in literature is given in an explicit form, with the diverse limit cases analysed in detail. In some of these limit cases, new expressions are also obtained which predict the existence of interfacial waves. In the other cases, when already reported results exist, a comparison with them is done. Some physical interpretations are derived from the limit cases. The influence of mechanical, electrical and magnetical imperfect contacts are shown in some numerical examples.
