Atmospheric Non-Thermal Plasma Sources

Atmospheric non-thermal plasmas (ANTPs) have received a great deal of attention in the last two decades because of their substantial breakthrough in diverse scientific areas and today technologies based on ANTP are witnessing an unprecedented growth in the scientific arena due to their ever-escalating industrial applications in several state-of-the-art industrial fields. ANTPs are generated by a diversity of electrical discharges such as corona discharges, dielectric barrier discharges (DBD), atmospheric pressure plasma jet (APPJ) and micro hollow cathode discharges (MHCD), all having their own characteristic properties and applications. This paper deals with some fundamental aspects of gas discharge plasmas (GDP) and provides an overview of the various sources of ANTPs with an emphasis on dielectric barrier discharge.
