Bleustein–Gulyaev waves in a finite piezoelectric material loaded with a viscoelastic fluid

A generalized analytical approach for the propagation of Bleustein–Gulyaev wave in a piezoelectric material loaded on its surface with viscoelastic fluid is established this paper. The waveguide subjected to various glycerol concentrations. Maxwell and Kelvin–Voigt models are used describe viscoelasticity fluid. Exact dispersion equation obtained cases both electrically short circuit open by solving equilibrium equations materials Stokes effect phase velocity attenuation several frequencies highlighted. influence key parameters such as substrate thickness also studied. These investigations can serve benchmark solution design sensors.
