(Color online) Performance of the GBS as a function of , for the four realizations denoted in the text as cases , , , and where the expansion parameters are: Case : , giving . Case : , giving . Case : As in case but with giving . Case : As in case but with . (a) The number of beams. (b) The spectral spread . (c) The relative error. We also show case which corresponds to case but with the GBs replaced by the CSBs.

(Color online) Ray trajectories for the numerical example: The left-hand panel shows the wave speed profile, while the right-hand panel shows the ray trajectories. Note the horizontal line , along which the field is plotted in Fig. 3.

(Color online) A comparison of the GBS and the ray solutions along the line in Fig. 2 at . (a) The field along the entire line. (b) Zoom on the caustic region. Note that the GBS has a smooth transition at the caustic, and it models the fine structure of the field afterwards, due to the three-ray interference.
