FIG. 1.

Experimental setup. An ultrafast scanner is connected to the probe (the transducer array) applied on one side of the phantom. The plane shear waves are generated perpendicularly to the probe with a rigid plate connected to a vibrator.

FIG. 2.

Attenuation coefficient vs the central frequency squared in an agar-gelatin phantom (5% gelatin concentration).

FIG. 3.

Third harmonic amplitude as a function of the propagation distance . The dots represent experiments, the solid lines correspond to the analytical expression [Eq. (4)], and the dashed lines are numerical outputs.
