| Abstract: | The propagation characteristics in cylindrical axisymmetric plasma were analyzed and the dispersion equation was deduced under surface waves models.The curves of wave-vector varying with plasma parameter,permittivity,structure size,frequency were given.The result of analysis shows that the propagation characteristics can be controlled by plasma parameter,permittivity and structure size. |
