    "abstract": "Pulsed Bessel beams of light propagating in free-space experience diffraction\neffects that resemble those of anomalous dispersion on pulse propagation. It is\nthen shown that a pulsed Bessel beam in a normally dispersive material can\nremain diffraction- and dispersion-free due to mutual cancellation of\ndiffraction and group velocity dispersion. The size of the Bessel transversal\nprofile for localized transmission is determined by the dispersive properties\nof the material at the pulse carrier frequency.",
