摘要
Acoustomigration is a well-known phenomenon, which may occur in Surface Acoustic Wave (SAW)-devices operating at high driving levels. Based on previously published reports [1-3] about calculation of the acoustic power, dynamic stresses and displacements in a homogenous isotropic A1-layer for a given driving, condition, we expand this method for the calculation of the SAW-induced stress in an electrode of a SAW-device. The quantitative calculation of this stress is based on the combination of the widely used P-Matrix based model, which yields the distribution of the potential power [2] for a given driving level and a FEM tool [4], which provides the relative stresses inside an electrode.
