| Abstract |
Love wave propagation in the conductive polymer structure is investigated in this study. The silicone rubber polymer of finite thickness is used in the guiding layer with conductive and viscous
effects. The functionally graded lithium tantalate with piezoelectric effect is taken in the substrate. The
propagation behavior of the Love wave is examined under the influence of the external force, sinusoidal diversity (SSD), conductivity, and viscoelasticity of the polymers. The impulsive force due to point
source is considered at the interface of the layer and substrate. The equations of motion in the presence of impulsive force are solved by Fourier transform and Green’s function technique. The dispersion
curve of the Love wave propagation is derived by using boundary conditions. The influence of the conductivity, viscosity, SSD parameters, and piezoelectricity on the propagation velocity of the wave is
examined for the first three modes of the Love wave. The dispersion equation reduced to the conventional form of the Love wave dispersion in particular cases. The derived results are appropriate for the
manufacturing and design of the surface acoustic wave (SAW) device, transducer, and sensors. Moreover, the results may be useful to enhance the performance of the surface acoustic wave devices and sensors. |
