Influence of the external electric field on propagation of lamb waves in piezoelectric plates

The influence of the electric field on the properties of the Lamb and SH-waves in piezoelectric Bi 12 GeO 20 and La 3 Ga 5 SiO1 4 crystal plates has been investigated. Using basic equations and boundary conditions, the formulas for computer simulation have been obtained. The effect of acoustic modes...

Zusammenfassung:The influence of the electric field on the properties of the Lamb and SH-waves in piezoelectric Bi 12 GeO 20 and La 3 Ga 5 SiO1 4 crystal plates has been investigated. Using basic equations and boundary conditions, the formulas for computer simulation have been obtained. The effect of acoustic modes hybridization has been considered.
