  We investigate the propagation of electronic waves described by the Dirac
equation subject to a L\'evy-type disorder distribution. Our numerical
calculations, based on the transfer matrix method, in a system with a
distribution of potential barriers show that it presents a phase transition
from anomalous to standard to anomalous localization as the incidence energy
increases. In contrast, electronic waves described by the Schr\"odinger
equation do not present such transitions. Moreover, we obtain the phase diagram
delimiting anomalous and standard localization regimes, in the form of an
incidence angle versus incidence energy diagram, and argue that transitions can
also be characterized by the behavior of the dispersion of the transmission. We
attribute this transition to an abrupt reduction in the transmittance of the
system when the incidence angle is higher than a critical value which induces a
decrease in the transmission fluctuations.
