In this work, we analyze the interaction of moving charged particles with bulk and surfaceplasmons in a semi-infinite material. For planar surfaces, and in the frame of a semi classical dielectricformulation, we analyze the differences and similarities that arise when we compare incoming and outgoingtrajectories in oblique trajectories. We describe an oscillatory structure that only appears in the bulkcontribution to the energy lost by an incoming projectile, and analyze how this in-out asymmetry dependsof the incidence angle.
