  We study the scattering properties of topological solitons on obstructions in
the form of holes and barriers. We use the 'new baby Skyrme' model in (2+1)
dimensions and we model the obstructions by making the coefficient of the baby
skyrme model potential - position dependent. We find that that the barrier
leads to the repulsion of the solitons (for low velocities) or their complete
transmission (at higher velocities) with the process being essentially elastic.
The hole case is different; for small velocities the solitons are trapped while
at higher velocities they are transmitted with a loss of energy. We present
some comments explaining the observed behaviour.
