大气压空气放电的电极结构是影响放电性能的关键因素之一。在本研究中，利用双面印刷电路板的方形格子结构，在大气压下产生表面介质阻挡空气微放电。报道了晶格宽度对放电性能的影响。采用数字图像处理方法对SDBAMD的均匀性进行了评价。我们的测量结果表明，SDBAMD的功率和点火电压显着依赖于接地电极的配置。数字图像处理结果表明，栅宽对放电均匀性影响很大，当栅宽为2.0mm时放电最均匀。基于COMSOL的数值模型表明，增加晶格宽度会导致接地电极附近的电场增加，从而导致晶体结构的改变。
The electrode configuration of atmospheric pressure air discharge is one of the key elements that have significant effects on the discharge properties. In this study, double-sided printed circuit boards with square-shaped lattice structure are used to generate surface dielectric barrier air micro-discharge (SDBAMD) at atmospheric pressure. The effects of the lattice width on the discharge properties are reported. The uniformity of the SDBAMD is evaluated by adopting the digital image processing method. Our measurements show that the power and ignition voltage of the SDBAMD significantly depended on the configuration of the grounded electrode. The digital image processing results show that the uniformity of the SDBAMD is severely affected by the lattice width, and the most uniform discharge is achieved at the lattice width of 2.0 mm. The numerical model based on COMSOL demonstrated that increasing the lattice width can lead to an increase in the electric field in the vicinity of the grounded electrode and ...
