Abstract
In the present study, anti-plane wave propagation has been considered in a piezoelectric viscoelastic composite medium where the surface has been coated with an infinitesimally thin and perfectly conducting electrode which is grounded. The frequency equation has been obtained analytically and the result has been found in well agreement with the classical B-G wave frequency equation which validates the result. Moreover, Semi-Analytical Finite Element using Perfectly Matched Layer (SAFE-PML) method has been adopted in order to deduce frequency equation. Numerical computation and graphical illustration have been done in order to study some influencing parameters. Both frequency equations obtained through analytical method and SAFE-PML method have been compared through graphs which also validate the obtained results.
