摘要：

Enhanced transmission of electromagnetic radiation through overdense, hot, unmagnetized plasmas has been observed via particle in cell (PIC) simulations. This effect is explained in terms of a fraction of the thermal electrons oscillating in the electrostatic potential of the plasma slab ions at a frequency close to the laser frequency. These electrons are capable of resonantly transporting transverse electric currents across the plasma. As these electrons reach the far end of the slab, the currents cause electromagnetic radiation at the laser frequency to be given off. (C) 2000 American Institute of Physics.
