Show more >Transmission of digital data in solid structures is effective in many industrial applications such as nuclear, aerospace and smart vehicles. Traditional wireless communication using electromagnetic waves becomes ineffective in the presence of metals due to Faraday shielding. Ultrasonic guided waves, such as Lamb waves, may be an alternative solution for communicating through metallic structures and may provide also useful information about the health of the structure itself. The objective of this work is to give a proper analogy scheme between telecommunication and ultrasound domains by doing experimental tests on healthy and defected aluminium plates. To ensure this analogy, an experimental platform for ultrasonic guided wave communication is built and an automated application using Matlab Graphical User Interface (GUI) is developed for modulation and demodulation. Different experimental tests on healthy plates are realised at first for Amplitude Shift Keying (ASK), On-Off Keying (OOK) and Binary Phase Shift Keying (BPSK) to chose the best modulation technique at optimal bit rate. After this, a demodulation algorithm based on cross- correlation concept from signal processing is developed and tested to ensure communication in defected plates. Results show that digital data can be recovered even in the presence of a large defect in the transmission channel.Show less >
