The electrical characteristics of DBD have been studied using four different barriers. These barriers are Pyrex glass, Mylar, porous alumina Al2O3 plates and ceramic plates of composition (50% MgO:50% Al2O3). It has been found that the type and the internal composition of the dielectric barriers affect the formation of the DBD modes. Using glass or Mylar as a dielectric causes the formation of the filamentary DBD mode. While using porous alumina plates leads to the generation of the discharge in APGD mode. A quasiglow mode is obtained when a ceramic of composition (50% MgO:50% Al2O3) is used. The effect of using one dielectric barrier, on the DBD characteristics has also been studied. Antisymmetric behavior of the current waveform is obtained when one dielectric barrier is placed on the life electrode.
