Results of electrical and spectroscopic diagnostics of dielectric barrier discharges by applying ceramic plates made of high permittivity material are presented. The spectroscopic diagnostic is based on analysis of spectral and spatial distribution of the hydrogen H alpha emission in the gas gap. From these measurements, e.g. the distributions of electric field strength and kinetic energy of excited hydrogen atoms in the discharge volume have been determined.
