Laboratory Experiments in Surface Acoustic Wave Devices and Their Applications

This project relates to the development of three novel laboratory experiments for electrical engineering seniors enrolled at the Polytechnic Institute of New York introducing them to surface acoustic wave (SAW) devices and their applications. Major developments in this new technology have taken place during the past decade. SAW devices now play a significant role in the signal processing area and industries´ strong interest in this new technology is now evident. The first experiment in the series demonstrates the fundamental behavior of SAW devices using the delay line structure. The second experiment relates to the measurement of the complex impedance of the SAW interdigital transducer. The third experiment demonstrates how the SAW device can be used to perform the function of convolution and correlation.
