Numerical Reproduction of Spatio-Temporal Evolution of Surface Plasmon Polaritons at Dielectric-Plasma Interface

Discharges in planar-type overdense plasmas caused by resonant excitation of surface plasmon polaritons (SPPs) are presented. The spatio-temporal evolution of surface waves of SPPs at the dielectric-plasma interface is reproduced numerically. It is found that different discharge light patterns are excited by different spatio-temporal wave fields. Moreover, the corrugation surface included in the proposed plasma sources plays a significant role in producing large-area uniform plasmas.
