| Abstract: | This paper investigates shear horizontal(SH) waves propagating in a periodically layered structure that consists of piezoelectric(PE) layers perfectly bonded with piezomagnetic(PM) layers alternately.The explicit dispersion relations are derived for the two cases when the propagation directions of SH waves are normal to the interface and parallel to the interface,respectively.The asymptotic expressions for dispersion relations are also given when the wave number is extremely small.Numerical results for stop... |
