| Abstract |
The influence of transmission of Love-type waves through a layer of functionally graded
piezoelectric material (FGPM) placed within a pre-stressed piezoelectric layer and irregular viscous
sandy half-space under hydrostatic stress has been discussed analytically. The irregularity has been
opted as rectangular for the lower viscous sandy half-space. The Wentzel-Kramers-Brillouin method
is utilized to find an asymptotic solution of a 4th order differential equation with variable coefficients
and variable separation method is a critical tool in the upper layer and lower half-plane. In contrast,
in the intermediate layer, theoretical derivations are discussed by the WKB technique. Dispersion relation for a Love-type wave is established for electrically open cases and sort cases. An impact of different parameters used in the problem on the phase velocity of a Love-type wave has been depicted graphically. This study is beneficial for constructing and improving surface acoustics wave (SAW) devices.
Some particular cases have also been demonstrated for the validation of the problem. Graphs of phase
velocity versus wave number have been presented. |
