根据潘宁气体放电的物理特性,定性分析了等离子体天线中氦氩潘宁气体放电的特性,实验测量了充满氦氩潘宁气体的等离子体天线与充满纯氦或纯氩等离子体天线的等离子体长度、等离子体密度,得出等离子体天线中充入氦氩潘宁气体时,在同等条件下能使等离子体天线的有效长度更长,等离子体密度更高。等离子体密度对天线的辐射效率和隐身性能影响很大,因此研究氦氩潘宁效应存在时表面波等离子体柱的等离子体长度与所加射频功率的关系和等离子体密度沿天线的分布对于提高天线的辐射效率和隐身性能至关重要。
According to the physical characteristics of Penning gas discharge, the characteristics of the gas discharge of the helium-argon Penning plasma in the plasma antenna are qualitatively analyzed. The plasma of the plasma antenna filled with helium-argon Penning gas and the plasma filled with the pure helium or pure argon plasma antenna are experimentally measured The length of the plasma and the density of the plasma indicate that when the plasma antenna is filled with the helium-argon Penning gas, the effective length of the plasma antenna can be longer and the plasma density can be higher under the same conditions. The plasma density has a great influence on the radiation efficiency and the stealth performance of the antenna. Therefore, the relationship between the plasma length of the surface wave plasma column and the applied RF power and the distribution of the plasma density along the antenna in the presence of the Penning effect of helium and argon are improved Antenna radiation efficiency and stealth performance is crucial.
