... Focusing of Finite-Amplitude Waves at Fold Caustics . ... The focusing of acoustic waves at a fold caustic is studied experimentally for different amplitudes   of the incident signals. This focusing occurs, for instance, for the sonic boom in case of aicraft   manoeuvres. ... The first stage consists in determining the signals to be emitted by an array   of piezoelectric antennae in order to obtain the field associated with the caustic to be   synthesized, i.e. the Airy function. ...
