Brief Review: Characteristics and Applications of Homogeneous Atmospheric Pressure Dielectric Barrier Discharge

Dielectric barrier discharge (DBD) can generate low temperature plasma under atmospheric pressure, with great research value and bright application prospect. Compared with filamentary DBD, homogeneous DBD has obvious advantages such as the mildness and uniformity of discharge. This paper provided a brief review of DBD research history and paid considerable attention to homogeneous DBD at atmospheric pressure. By summarizing the latest diagnostic technology and numerical simulation methods, this paper reported some of the most important results of DBD characteristics and mechanism in recent decades. In addition, typical DBD plasma applications in biomedical fields, food safety, environmental pollution control were introduced. Technical problems that came up in present DBD research and application development were analysed. And the outlook for the DBD technology was given.
