Elastic waves are often used in non-destructive testing (NDT) to detect material defects in metal pipes. In NDT methodology, high-frequency elastic waves are launched into a pipe with an ultrasonic transducer. Material defects comparable in size to wavelength scatter ultrasonic waves, and analysis of scattered signal allows quantifying the defect and its location. As a variation of NDT technology, ultrasonic transducers placed at the ends of a pipe, and operating at wavelengths larger than typical micro-crack sizes, can act as a transmitter and receiver of information. By modulating transducer signal to send information encoded with elastic waves across a metal pipe, we attempt to create a communication channel. By taking advantage of existing piping infrastructure of thermal hydraulic systems, such communication links would allow the transmission of information across physical barriers in a nuclear facility.
