[3Fa02] Shape-control of surface-launched plasma bullets by designing spatial profiles of applied voltage

*Tatsuru Shirafuji1, Jun-Seok Oh1 (1. Osaka Metropolitan University)

Surface-launched plasma bullets (SLPBs) can be launched vertically from a planar dielectric plate unlike conventional APPJ. We discuss on the possibility of generating sheet-shaped plasma bullets using this method. We performed numerical simulations of SLPBs under artificially designed potential profile on the electrode although it is very difficult task in experiments. Our numerical simulation of SLBPs revealed that SLPBs can be dome-shaped sheet when applied potential has Gaussian profile on the electrode.
