A strong in-plane magnetic field drastically alters the low-energy spectrumof bilayer graphene by separating the parabolic energy dispersion into twolinear Dirac cones. The effect of this dramatic change on the transportproperties strongly depends on the orientation of the in-plane magnetic fieldwith respect to the propagation direction of the charge carriers and the angleat which they impinge on the electrostatic potentials. For magnetic fieldsoriented parallel to the potential boundaries an additional propagating modethat results from the splitting into Dirac cones enhances the transmissionprobability for charge carriers tunneling through the potentials and increasesthe corresponding conductance. Our results show that the chiral suppression oftransmission at normal incidence is turned into a chiral enhancement when themagnetic field increases, thus indicating a transition from a bilayer to amonolayer-like system at normal incidence. Further, we find that the typicaltransmission resonances stemming from confinement in a potential barrier areshifted to higher energy and are eventually transformed into anti-resonanceswith increasing magnetic field. For magnetic fields oriented perpendicular tothe potential boundaries we find a very pronounced transition from a bilayersystem to two separated monolayer-like systems with Klein tunneling emerging atcertain incident angles symmetric around 0, which also leaves a signature inthe conductance. For both orientations of the magnetic field, the transmissionprobability is still correctly described by pseudospin conservation. Finally,to motivate the large in-plane magnetic field, we show that its energy spectrumcan be mimicked by specific lattice deformations such as a relative shift ofone of the layers. With this equivalence we introduce the notion of an in-planepseudo-magnetic field.
