[email protected] Received 25 September 2013, revised 7 January 2014 Accepted for publication 9 January 2014 Published 7 February 2014 Abstract A diffuse discharge is produced in atmospheric pressure air between porous alumina dielectric barriers using low-frequency (60 Hz) alternating current. To study its formation mechanism, both the discharge current and voltage are measured while varying the dielectric barrier porosity (0%, 48% or 85%) and composition (99% Al2O3 ,99% SiO2 or 75% Al2O3 + 16% SiO2 + 9% other oxides).
