Resumen
It is well known that Bessel beams and the other families of propagation-invariant optical fields have the
property of self-healing when obstructed by an opaque object. Here it is shown that there exists another
kind of field distribution that can have an analog property. In particular, we demonstrate that a class of
caustic wave fields, whose transverse intensity patterns change on propagation, when perturbed by an
opaque object can reappear at a further plane as if they had not been obstructed. The physics of the
phenomenon is fully explained and shown to be related to that of self-healing propagation invariant
optical fields.
