| 摘 要： | 通过研究等离子体作为电磁波传导媒质的基本物理原理,可知表面波激发的柱形等离子体在特定条件下,可以代替传统的金属用于构成最基本的辐射振子。针对此等离子体辐射体为有源天线的特点,结合传输线阻抗匹配的原理,设计实验对其输入阻抗进行测量,得到符合理论分析的初步结果。对等离子体作为辐射体传输电磁波的研究具有重要的参考价值。

| Abstract: | Based on the basic principle of propagation property of electromagnetic wave in plasma,it’s well known that the surface wave driven column plasma can replace metal as the guiding medium in radio frequency antennas in certain applications.However,it’s difficult to measure the parameters of plasma antenna due to the driven power used for producing and maintaining the plasma in this special antenna.Thus an experiment to measure plasma antenna input impedance has been designed,using the principle of impedance matching in transmission line.Experimental result accords with the analysis.This result will play an important role in the application of plasma in the antenna transmission. |
