Abstract
A surface acoustic wave device () is provided using a layered substrate system with a special material and a special cut of a piezoelectric thin film () selected for utilizing Rayleigh mode. The proper choice of the material and the cut of the piezoelectric thin film leads to a low velocity of the excited wave mode, which allows the usage of smaller devices without deteriorating other performance parameters according to specifications.
