Advantages

Petal-like multiple surface ionization waves formed on both convex and concave surfaces

Electron density and electron temperature above the surface increase when changing from convex to concave

Increasing pulse amplitude or decreasing pulse rising edge duration raises electron density, electron temperature, and electron impact ionization source
