Acoustic wavelength effects on the propagation of SAW on piezo-crystal and polymer substrates

The design, fabrication and characterization of Surface Acoustic Wave (SAW) delay lines on piezo-crystalline and polymer substrate is outlined in this paper. The SAW delay lines consist of two sets of Inter-Digital Transducers (IDT) separated by a certain distance on the surface of the piezoelectric...
