It is shown that under certain conditions the radiation leads to appearance of directed transport linked to an underlining strange attractor. The direction of transport can be efficiently changed by radiation polarization. The experimental realization of this effect in asymmetric antidot superlattices is discussed.revtex, 4 pages, 6 figsMesoscale and Nanoscale PhysicsSoft Condensed MatterStatistical MechanicsChaotic Dynamicstext
