Abstract
Wave fields near caustics may be expressed very simply when one calculates them in the time domain rather than in the more usual frequency domain. The technique is described allowing one to calculate the form of the seismic signal that propagates along the ray passing a caustic. Practical use of the technique is illustrated for the case of a caustic cusp.
