Kinetic effects during the interaction between high density microplasma and electromagnetic wave
Abstract
The interaction between a high-density microplasma and a high-power electromagnetic wave is studied by a one-dimensional Particle-in-Cell Monte Carlo collision model coupled with Maxwell's equations. We find the value of the amplitude of the wave field above which a fully ionized plasma is generated on the picosecond time scale. This fully ionized plasma is obtained only in the skin layer, while the ionization degree of the plasma bulk is ∼20%. The simulation results show that such non-homogeneous distribution of the plasma and gas density influences significantly the heating of plasma electrons and time evolution of the electron energy probability function.
