“…The viscosity and density of the liquid slow down the wave propagation speed and thus create a detectable phase difference with respect to a reference wave [42][43][44][45][46]. Additionally, BG waves have also been shown to work as gyroscopes [47,48].…”

We present a novel compact electric permittivity sensor that exploits Bleustein-Gulyaev (BG) waves propagating along the surface of shear-poled piezoelectrics. We formulate the dynamic nonlinear electromechanical partial differential equations of motion governing wave propagation under electromagnetically quasistatic conditions. The permittivity of the medium-under-test was found to influence the sensor eigenvalues, enabling the implementation of a frequency-shift permittivity sensor. Solution of the equations of motion demonstrates resonance of the first and third modes when excited using an IDT. We fabricated two sensor prototypes on shear-poled PZT4 and LiNbO3 substrates and used a Vector Network Analyzer to observe the shift in their fundamental natural frequency in the presence of various media-under-test. S11 measurements show deterministic and repeatable shifts in the resonant frequency of the first mode of the LiNbO3 sensor measured at △f1=3.51 MHz for ethanol and △f1=7.49 MHz for deionized water where the bare surface frequency was initially at f1=25.27 MHz.

“…Additionally, another perspective of interest with regard to the multilayered media where researchers hugely invested is the propagation of waves amid the presence or influence of external excitations. For instance, the investigation of electromechanical propagation in pre‐stressed layered piezoelectric materials, 17 the dispersion of shear waves in piezoelectric layered cylinders with initial stresses, 18 and the influence of magnetic and rotational effects on the wave propagation in elastic three‐layered laminates 19 . We have equally got other relevance including the SH waves propagation in nonlinear heterogeneous plates, 20 the effect of viscous damping on the propagation of waves in three‐layered composites, 21 and the diffraction of electromagnetic waves in bi‐isotropic homogeneous media, 22 to mention a few.…”

In this manuscript, the anti‐plane shear motion of an asymmetric three‐layered inhomogeneous elastic plate is examined. An asymptotic approach is employed for the present investigation. Both thgeneralized and unified dispersion relations within the long‐wave low‐frequency range have been successfully determined. The obtained unified dispersion relation is investigated taking into account the recently analyzed material contrast for layered plates with mixed stiff‐soft layers of different material properties. The asymptotic formulae for the respective fields in addition to the determination of approximate equations of motions have also been presented. A comparative study with the symmetric plate is made; being a special case of the asymmetric plate under consideration. In the end, we provide some deductions and concluding remarks.
