Abstract
We study the property of propagation beams disturbed by an opaque obstacle. The fronts of the Hankel waves are disturbed and beyond the obstacle they are reconstructed. We report the observation of two shadow produced by the obstacle, and the fact that the Bessel beam is formed of ingoing and outgoing conical waves. We numerically solve the Helmholtz equation to show the evolution and the reconstruction of the Bessel beam and we demonstrate the correspondence of these results with the experimental part.
