In this work, the propagation of the surface ionization wave (SIW) in the nanosecond pulsed surface dielectric barrier discharge with different dielectric materials and pulse repetition rates is investigated. The current waveforms at different locations along the route of the SIW propagation are obtained, based on a specially designed ground strip array geometry. The temporal evolution and spatial distribution of the electric field during the SIW propagation are measured by using the electric field induced second harmonic (EFISH) generation method. The distribution of the residual surface potential after the discharge is mapped with a Kelvin electrostatic probe, which verifies both the existence of the residual electric field and its opposite direction to that during the SIW propagation. It is found that with the dielectric material on which the surface charges decay faster, there are the well-pronounced primary and secondary SIWs with a higher velocity on the voltage rising edge and both the peak current and the peak electric field are also higher, with a less spatial attenuation along the SIW propagation route. It is demonstrated that the residual surface charges with the same polarity as the high-voltage pulse suppress the development of the surface ionization wave.

纳秒脉冲表面介质阻挡放电中的表面电离波传播：介质材料和脉冲重复率的影响

在这项工作中，研究了表面电离波 (SIW) 在具有不同介电材料和脉冲重复率的纳秒脉冲表面介质阻挡放电中的传播。基于专门设计的接地带阵列几何结构，可以获得沿 SIW 传播路径不同位置的电流波形。通过使用电场感应二次谐波 (EFISH) 生成方法测量 SIW 传播过程中电场的时间演变和空间分布。放电后残余表面电位的分布用开尔文静电探针绘制，它验证了残余电场的存在及其与SIW传播过程中的相反方向。发现表面电荷衰减较快的介电材料，在电压上升沿出现速度较快的初级和次级SIW，且峰值电流和峰值电场也较高，与沿 SIW 传播路径的空间衰减较小。结果表明，与高压脉冲具有相同极性的残余表面电荷抑制了表面电离波的发展。
