Abstract :
We investigate analytically the effect of the viscous dissipation of material on the dispersive and attenuated characteristics of Love wave propagation in a layered structure, which involves a thin viscoelastic layer bonded perfectly to an unbounded piezoelectric substrate. The effects of the viscous coefficient on the phase velocity of Love waves and attenuation are presented and discussed in detail. The analytical method and the results can be useful for the design of the biosensors or chemical sensors.
