Query: Monte-Carlo simulation of the coherent backscattering of electrons in a
  ballistic system   We study weak localization effects in the ballistic regime as induced by
man-made scatterers. Specular reflection of the electrons off these scatterers
results into backscattered trajectories which interfere with their
time-reversed path resulting in weak localization corrections to the
resistance. Using a semi-classical theory, we calculate the change in
resistance due to these backscattered trajectories. We found that the inclusion
of the exact shape of the scatterers is very important in order to explain the
experimental results of Katine et al. [Superlattices and Microstructures 20,
337 (1996)].
