摘要
等离子体天线因其具有许多独特的性质而受到各国军方的广泛关注。本文首先介绍了表面波等离子体天线的基本原理及组成,并根据同轴对称表面波沿等离子体柱轴向传播的色散关系,研究了等离子体碰撞频率以及等离子体频率对表面波波矢的影响。文章最后对影响等离子体碰撞频率以及等离子体频率的因素进行了分析。
Plasma antenna has abroad attracted attentions of armies since it has a great deal of unique characters. In this paper, the elementary theory for surface wave stimulating plasma antenna and the system structure of the antenna were presented firstly. Then the influence of plasma collision frequency and plasma frequency on the surface wave vector was studied according to the dispersion of the axisymmetric surface wave along the plasma column. Moreover factors which affect plasma collision frequency and plasma...
