Transmission of digital data using guided ultrasonic waves in solid plates
Résumé
Wireless communication systems are widely known particularly in telecommunication field, where simply, information can be transmitted without using any wires or cables. The wireless communication systems are mainly used for mobile communication and networking and not widely adopted in other mediums such as solid or liquid. Furthermore, using these different mediums for communication has become interesting when no other option is proposed, such as underwater communication or through solid metallic channels (cylinders or plates). The use of guided ultrasonic waves such as Lamb waves for solid medium may be an attractive solution since it can propagates through long distances. The objective of this work is to compare the behavior of different modulation and demodulation techniques at different frequencies and different bit rates by building an experimental platform for ultrasonic guided wave communication.
