Abstract :
The generation of reflected freely-propagating second harmonic SV wave at solid-solid interface is an interface nonlinear effect. It is anticipated that the bonding state of the interface will affect the effect. In this paper, the influence of the vibrating interface on the effect is studied. It is observed that the nonlinear reflective SV wave becomes amplitude modulation due to the vibration of the refractive media (PZT), whereas no modulation takes place for the linear reflective SV wave.
