摘要

在固-固界面处反射自由传播的二次谐波SV波的产生是一种界面非线性效应。预计界面的键合状态将影响其效果。本文研究了振动界面对振动效果的影响。观察到非线性反射SV波由于折射率介质(PZT)的振动而发生幅度调制，而线性反射SV波则不发生调制。

A nonlinear amplitude modulation phenomenon

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.
