Surface acoustic wave device use the properties of certain piezoelectric materials to propagate a signal, whose velocity can be modified by the presence of a metal on the surface. SAW device use surface acoustic wave in electronic components to provide a number of different functions, containing delay lines, filters, correlators and DC to DC converters. SAW devices are widely used in many applications, with various configurations, but one particular application of SAW device has been in the communication technology due to their small size, light in weight, low cost and high performance, which are needed there simultaneously. In seismology, SAW devices are important instruments for discharging the waves that travel on the Earth’s surface and is of major importance for detection of seismic waves produced from earthquakes.
