Rotation effect on parameters of elastic waves propagating in substrate of SAW-based solid-state gyros

Resumo

The paper proposes an analytical solution to the problem of elastic waves propagation in a structure comprising a carrying foundation on which a piezoelectric layer is applied, and being subjected to constant rotation. Relations for calculating the dependency of elastic waves parameters on the rotation rate are obtained. Numerical simulation results are presented. The possibility of applying the results in solid state gyros based on surface acoustic waves (SAW) is considered.
