Interaction of the powerful electromagnetic ray of the limited radius with a dense plasma layer was studied viacomputer simulation using the PIConGPU software package in 3D geometry. The characteristic modes of channel formation in the barrier (namely laminar and turbulent) are described. Turbulent mode can be associated with the fast transillumination, observed in laboratory experiments. The channel formation time as a function of the incident beam power and the plasma layer density is studied. Information transparency is also observed at the third harmonic of the incident wave.
