Comparisons of measurements (100%-bandwidth excitation) with simulation. Cross section in the elevation plane for: (a) simulation and (b) measurement (W= 2.9 mm, α= 27° and ymin= 7.16 mm); (c) beam profile on center axis; (d) beam profile in the elevation direction at focal distance (zpeak = 18.5 mm); (e) comparison of the pressure waveforms at zpeak (the insert corresponds to the pressure waveforms obtained with a 50%-bandwidth excitation); (f) Comparison of simulated and measured electrical impedance of the LF transducers.
