  Real-world samples of graphene often exhibit various types of out-of-plane
disorder -- ripples, wrinkles and folds -- introduced at the stage of growth
and transfer processes. These complex out-of-plane defects resulting from the
interplay between self-adhesion of graphene and its bending rigidity inevitably
lead to the scattering of charge carriers thus affecting the electronic
transport properties of graphene. We address the ballistic charge-carrier
transmission across the models of out-of-plane defects using tight-binding and
density functional calculations while fully taking into account lattice
relaxation effects. The observed transmission oscillations in commensurate
graphene wrinkles are attributed to the interference between intra- and
interlayer transport channels, while the incommensurate wrinkles show vanishing
backscattering and retain the transport properties of flat graphene. The
suppression of backscattering reveals the crucial role of lattice
commensuration in the electronic transmission. Our results provide guidelines
to controlling the transport properties of graphene in presence of this
ubiquitous type of disorder.
