| 摘 要： | 为优化表面波放电的狭缝天线阵设计,给表面波放电装置的设计提供理论依据,对狭缝天线布局进行了理论和仿真计算分析。结果表明,宽缝辐射的电磁场比纵缝强,同相激励天线辐射的电磁场比异相激励强,更容易击穿空气产生等离子体。基于磁场强度同相分布规律对已经采用的纵缝天线阵进行改进,纵缝按照两侧交互并间隔半个波导波长布置,各个纵缝均为同相,产生等离子体效果更好。

| Abstract: | In order to optimize the design of slot antenna array of surface wave discharge and provide theoretical basis for design of surface wave discharge device, the slot antennas have been calculated and analyzed. The results show that the electromagnetic field radiated by transverse slots is stronger than by longitudinal slots; the electromagnetic field radiated by co-phased antennas is stronger than by heterogeneous antennas, the former is easier to breakdown air and produce plasma. The longitudinal slot antenna array is improved based on the phase distribution of magnetic field intensity, in order to make every slot in phase to make produce plasma efficiently, longitudinal slot antennas are arranged on two sides with interval of half a wavelength. |
