Gas electric discharge induced by electromagnetic vibrator in quasi-optical microwave beam with significantly subcritical field level

Abstract

Experiments on the ignition of electric discharge in air in quasi-optical microwave beam with subcritical field level are performed using a linear half-wavelength electromagnetic vibrator fixed above screen. It is demonstrated that the plasma of the induced electric charge at air pressures that exceed a critical level has a relatively high gas temperature providing the ignition of propane–air mixture.
