| Abstract: | 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 frequency are theoretically examined. |
