| 摘 要： | 本文用磁流体力学的方法研究了等离子体环境下圆柱体开槽天线的辐射问题,推导了槽天线的方向图和阻抗的计算公式,计算了不同等离子体参量的横槽的方向图,并且把计算的结果与用不考虑纵波影响的复介电常数方法得到的结果进行了比较。

| Abstract: | The linearized fluid model was applyed to calculate the radiation patterns of slot antenna on infinite cylinder in presence of loss homogeneous, compressible, isptropic plasma with varied electron density, collision frequency, these patterns were also compared with the patterns based on cold plasma theory to analyse the influence of acoustic wave on radiation because linearized fluid model contains the affection of acoustic wave, but cold plasma don't. An analysis of influence of electron density and collision frequency on pattern was also givern. |
