Point-to-Plane Discharge on an Anisotropic Ceramic-Matrix Composite Layer at Atmospheric Pressure

In this paper is presented the recording of a point-to-plane dielectric barrier discharge in dry air, in which the dielectric layer has been replaced by a layer of anisotropic ceramic-matrix composite material (Streamer). An original high-intensity discharge is observed above a voltage threshold. The electrical parameters and the spatial structure of the discharge are presented. The energy deposition in the gas is compared to the one obtained for a purely dielectric layer (Al
