The Quasi-Harmonic Ultrasonic Polar Scan for Material Characterization: Experiment and Numerical Modeling Vrije Universiteit Brussel KU Leuven Universiteit Gent
Conventionally, the ultrasonic polar scan (UPS) records the amplitude or time of flight in reflection or transmission using short ultrasonic pulses for a wide range of incidence angles, resulting in a unique fingerprint of the critical bulk wave angles of the material at the insonified spot. Here, we investigate the use of quasi-harmonic ultrasound (bursts) in a polar scan experiment, experimentally as well as numerically. It is shown that the ...
