摘　　要：文章从麦克斯韦方程组出发,利用纵向场分量法,详细地推导了强引导磁场下等离子体波导中电磁场分量的表达式.作为示例,给出了充等离子体螺旋线中电磁场的解.在该文所得结果的基础上,结合各区域的边界条件,可进一步导出等离子体波导中电磁波传播的色散方程.In this paper, the expressions of the electromagnetic field components in a plasma waveguide immersed in a strong longitudinal magnetic field are derived in detail from the Maxwell＇s equations. As an example, the solution to the electromagnetic field in a plasma loaded helix type slow wave structure is given. The dispersion equation of the electromagnetic wave in the plasma loaded waveguide can be derived on the basis of the result mentioned previously and the boundary conditions in each region.
