  Charge carriers in single and multilayered graphene systems behave as chiral
particles due to the particular lattice symmetry of the crystal. We show that
the interplay between the meta-material properties of graphene multilayers and
the pseudospinorial properties of the charge carriers result in the occurrence
of Klein and anti-Klein tunneling for rhombohedral stacked multilayers. We
derive an algebraic formula predicting the angles at which these phenomena
occur and support this with numerical calculations for systems up to four
layers. We present a decomposition of an arbitrarily stacked multilayer into
pseudospin doublets that have the same properties as rhombohedral systems with
a lower number of layers.
