  We model electronic transport through a double quantum wire in an external
homogeneous perpendicular magnetic field using a scattering formalism built on
the Lippmann-Schwinger equation. In the scattering region a window is opened
between the parallel wires allowing for inter- and intra-wire scattering
processes. Due to the parity breaking of the magnetic field the ensuing subband
energy spectrum of the double wire system with its regimes of hole- and
electron-like propagating modes leads to a more structure rich conductance as a
function of the energy of the incoming waves than is seen in a single
parabolically confined quantum wire. The more complex structure of the
evanescent modes of the system also leaves its marks on the conductance.
