  We study the electronic transport of armchair and zigzag gated phosphorene
junctions. We find confined states for both direction-dependent phosphorene
junctions. In the case of armchair junctions confined states are reflected in
the transmission properties as Fabry-P\'erot resonances at normal and oblique
incidence. In the case of zigzag junctions confined states are invisible at
normal incidence, resulting in a null transmission. At oblique incidence
Fabry-P\'erot resonances are presented in the transmission as in the case of
armchair junctions. This invisibility or electronic cloaking is related to the
highly direction-dependent pseudospin texture of the charge carriers in
phosphorene. Electronic cloaking is also manifested as a series of singular
peaks in the conductance and as inverted peaks in the Seebeck coefficient. The
characteristics of electronic cloaking are also susceptible to the modulation
of the phosphorene bandgap and an external magnetic field. So, electronic
cloaking in phosphorene junctions in principle could be tested through
transport, thermoelectric or magnetotransport measurements.
