Love wave propagation in layered piezoelectric structures for sensor-based applications

Sayantan Guha
Abstract
Piezoelectricpiezoelectric (PEPE) materials are a special type of “smart” material with mechanical–electrical energy conversion properties, which are commercially harnessed in many industrial areas like ultrasonic detectors, transducers, NDT/NDE, sensors, actuators, Surface/Bulk Acoustic Wave (S/BAW) devices, LoveLove wavewave sensors, etc. The versatility of these applications make an in-depth analysis of the internal characteristics of PEPE materials quintessential. This acts as a prime source of motivation to perform the present analysis, where the transference of LoveLove wavewave in a layered structure comprising a PEPE layer overlying a PEPE half-space is the main point of focus, keeping LoveLove wavewave sensors, among other applications, in mind. Starting with the governing equations of the system, which involves highly coupled partial differential equations, the closed-form expressions of the dispersiondispersion relations for electrically open and electrically short cases are eventually obtained analytically using admissible boundary conditions assumed at the layer’s free surface, as well as the layer’s and the half-space’s interface. Numerical simulations and graphical demonstrations are performed to observe the nature of the dispersiondispersion curves when different combinations of PEPE materials are considered for the layer and the half-space, e. g., PZT-2, PZT-4, PZT-5A, PZT-5H, CdSe, BaTiO3, etc.
