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.
