“…When the propagation distance or the sample thickness was insufficient, similar behavior was observed for the measured β of water and aluminum [25,26]. The behavior of γ after total corrections is shown in Figure 7b as a function of input power level.…”

“…Furthermore, the y-intercept of the fitted line may not pass through the origin. The non-zero y-intercept indicates the amount of source nonlinearity included in the measurement system or the noise floor of the measurement system [ 25 ]. Therefore, the relationship plot of vs. obtained using the measurement data provides insight into the behavior of nonlinear solid samples and the stability of the measurement system against source nonlinearity.…”

“…The absolute measurement of the received displacement generally requires the use of a calibrated receiving transducer. In case of an air-coupled receiver, however, the reciprocity-based calibration [ 19 , 20 ] is very difficult to perform because of high attenuation in the air. Due to the difficulty of obtaining calibration measurements, it is possible to use an electrical output signal instead of the received displacement in the measurement of nonlinear parameters.…”

“…Detection of second harmonic generation measurements using longitudinal waves has been conducted with contact piezoelectric transducers [ 1 , 2 , 3 , 4 , 5 , 6 ], capacitive transducers [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ], and laser interferometers [ 15 , 16 , 17 , 18 ]. An absolute measurement of material nonlinearity is possible using either capacitive transducers [ 9 , 12 ] or contact piezoelectric transducers using a calibration procedure [ 19 , 20 ] in which the absolute displacement amplitude of the fundamental and second harmonic waves can be measured.…”

“…Nonlinear ultrasound methods often measure the second harmonic generation (SHG) to obtain a nonlinear parameter β, defined as the ratio of the second harmonic amplitude to the square of the fundamental wave amplitude, and draw conclusions about the material state. Nonlinear parameters can be measured, using longitudinal waves [7][8][9][10][11], Rayleigh waves [12][13][14], and Lamb waves [15][16][17]. Rayleigh waves require sufficient propagation distance to measure SHG; the measured nonlinearity is averaged over distance and cannot be localized.…”
