“…Recently, the propagation methodology of SH waves in a two different coupled structures for examples, piezoelectric-piezomagnetic, piezoelectricelastic, piezoelectric-semiconductor and piezoelectricpolymeric are considered for various hypotheses by many authors like, Liu et al (2010;Son and Kang, 2011;Piliposian et al, 2012;Vashishth and Dahiya, 2013;Zakharenko, 2013). The propagation of SH surface acoustic waves like the Bleustein-Gulyaev wave (Abd-Alla and Asker, 2016;Gua and Jin, 2015) and Rayleigh waves Abd-Alla and Alshaikh (2016), have exceptional significance for the design electronic and communication systems throughout the world.…”

Abstract:In this study, a mathematical model of the rotation effect on Shear Horizontally wave (SH-wave) propagation in a piezoelectric semispace covered by a semiconductor film is investigated. The semiconducting layer is rotating with a constant angular velocity and the interface between the piezoelectric substrate and the semiconductor layer is imperfectly bonded. Furthermore, the surfaces of the bilayer system assumed free of traction and electrically shorted or open. The governing equations of the dynamical displacement and electrical potential function under the effect of rotation are driven by solving the coupled electromechanical field equations of the piezoelectric half-space and the semiconductor film. In addition, the exact frequency equations of SH waves are derived. Next, the numerical examples are considered to clarify the effects of rotation and electromagnetic boundary conditions for the different values of the film thickness and wave number on the dispersion behaviors. Finally, the effect of rotation on the frequency equation is investigated in detail for piezoelectric material PZT-5H and the semiconductor silicon. The obtained results provide a predictable and theoretical basis for applications of piezoelectric and semiconductor structures to surface acoustic wave equipments.

Abstract. This paper investigates the shear horizontal surface acoustic wave (SH-SAWs) propagating in layered piezomagnetic/piezoelectric structures covered a microbeam array, which involves a thin piezomagnetic layer bonded perfectly to an unbounded piezoelectric substrate. The beams are modeled by the Euler-Bernoulli theories when they are bending during the piezomagnetic/piezoelectric structures in shear motion. The explicit formulations of SH-SAWs dispersion relations in such layered structure with consideration of magnetoelectrically open and shorted cases are derived. The effects of the microbeam array on the phase velocity are analyzed. The numerical results are presented and discussed. From the results, we can find that the effects of microbeams on the properties of the SH-SAWs are remarkable. The phase velocity decrease with the non-dimensional wave number and increase with the number of microbeams and the thickness of piezomagnetic layer. The analytical method and the results in the paper could be useful to the design of the chemical sensors of magnetoelectric materials. IntroductionIt is well known that the composite materials consisting of piezoelectric (PE) and piezomagnetic (PM) have the ability to convert energy between magnetic and electric fields which is not present in single-phase piezoelectric or piezomagnetic materials [1][2]. For this reason, PM-PE composites are potential candidates for magnetic sensors, transducers and microwave devices, e.g. delay lines, magnetic field probes, damage detectors, medical ultrasonic imaging, and resonators, etc. These applications are done with wave propagations and vibrations in PM-PE composites, and so their dynamic behavior is the first concern in design as well as in performance. A number of investigations have been reported about the wave propagation problems in such composites [3][4].We all known a large number micro-or nano-scale beam arrays have been made by using different techniques due to the extensive effort on micro-and nano-technologies [5][6]. These new structures have great potentials for new devices such as efficient microneedles, dynamic tuning of surface wetting, microelectromechanical systems (MEMS) actuators and resonators, etc. There are strong needs to study the effects of microbeams on vibrations of structures or wave propagation in structures due to the design of resonators, sensors and actuators. Li et al discussed the collective buckling of nonuniform nanobeams interacting through an elastic substrate [7]. Lin et al considered the effects of surface deformation on the collective buckling of an array of rigid beams on an elastic substrate [8]. Liu et al investigated shear vibration of a rotated Y-cut quartz crystal plate carrying an array of microbeams with their bottoms fixed to the top surface of the plate [9]. From the paper, we can find that the plate was modeled by the theory of anisotropic elasticity and the beams were modeled by the Euler-Bernoulli theory for beam bending, and a frequency equation that determines the resonan...
