摘要
分析了外磁场中电磁波沿空心圆柱等离子体波导的传播特性．首先给出边界条件的矩阵方程，利用矩阵的有关性质导出了问题的特征方程，采用精确求解特征方程的数值法，分析了波导传播常数随等离子体厚度、电子密度、碰撞频率和外加磁场的变化规律．
The electromagnetic wave propagating along a circular hollow plasma wave-guide immersed in an external magnetic field is presented. Because of the boundaryconditions at all interfaces can be represented by the matrix equations, the char-acteristic equation can be obtained by using the matrix manipulation- The effectsof the plasma thickness of cladding, electron cyclotron frequency, and collision fre-quency on attenuation of the waveguide are investigated.
