等离子体圆柱波导的频率相关性

The Frequency Pertinence of Plasma Cylindrical Waveguides

通过给出的等离子体圆柱波导的精确特征方程,讨论了特征方程的特征值对频率的依赖。并且对特征值与厚度因子(α)的关系进行讨论,给出了在α1时的特征方程,该方程计算简便。进一步运用α1时的特征方程的解,提出了一种求解严格特征方程之特征值的近似方法。

This paper discussed the dependence of the characteristic value of characteristic equation on frequency for the given precise characteristic equations of plasma cylindrical waveguides. At the same time, the relationship between the characteristic value and thickness factor were discussed and the characteristic equations were obtained, which is easy computed. With the solutions of characteristic equations, we advanced an approximative algorithm for solving precise characteristic equations.
