Lateral beampatterns, theory, and simulation. The broadband Gaussian model formula is very close to those simulated in Field II for different bandwidths, while the narrowband Gaussian model becomes invalid as the bandwidth increases. The comparison is shown in log scale, and details of the small differences are displayed in the bottom-left insert.
