This model simulates a negative dielectric barrier discharge under a point-to-plate electrode configuration. Two solid dielectric layers are inserted into the air gap. A negative voltage of 2.5 kV is applied to the cathode electrode, initiating a corona streamer that propagates and generates a current pulse. The resulting negative charge carriers accumulate at the gas–solid interface, altering the electric field. Ultimately, a stable negative surface discharge is formed. The simulated discharge current and surface charge distribution at the gas–solid interface show excellent agreement with experimental results.
