| The non-linear AC transport trough a quantum wire with
an impurity in the presence of finite-range
electron-electron interactions is investigated. We
discuss the influence of the spatial shape of the
electric field onto the transport properties of the
system and find that the scaling behavior of the
occupation probability of the sidebands depends on the
range of the voltage drop. We observe a cross-over
between the Tien-Gordon like scaling of the sidebands
and a regime in which the scaling reflects the ranges
of both, the electron- electron interaction and the
electric field.
