  We theoretically study electronic transport through a region with
inhomogeneous Rashba spin-orbit (RSO) coupling placed between two normal
regions in a monolayer graphene. The inhomogeneous RSO region is characterized
by linearly varying RSO strength within its borders and constant RSO strength
in the central region. We calculate the transmission properties within the
transfer matrix approach. It is shown that the amplitude of conductance
oscillations reduces and at the same time the magnitude of conductance
increases with increasing border thickness. We also investigate how the Fano
factor can be modified by the border thickness of RSO region.
