Abstract

We present an “Ab Initio“ transient analysis of acoustic wave generation in piezoelectric materials which takes account of second order effects. The computer program we have developed for that purpose solves the fundamental differential equations in two space dimensions with the corresponding mechanical displacements and the electrical potential as dependent variables by a semi-implicit finite difference scheme rather than by wave approximations. This has become possible with acceptable usage of computer resources only by introducing a novel form of boundary conditions for the quasi infinite sagittal plane to avoid reflection phenomena. We present numerical results for YZ-LiNb03 and ST-Cut of Quartz.
