Transillumination of the dense plasma barrier by the strong beam of electromagnetic waves: computer simulation

Transillumination of a dense plasma barrier by a strong electromagnetic wave beam has been studied via simulation using the PIConGPU software package. Formation of the channel with reduced plasma density, predicted theoretically and detected experimentally, was observed. For a higher power incident beam, plasma turbulent dynamics has been observed, which leads to its "fast" transillumination. The simulation results did not confirm the theoretically proposed mechanisms of "fast" transillumination. (author)
