摘要
利用线性场理论和螺旋线的导带模型,对填充等离子体的带状螺旋线进行了严格的场分析.在给出各区域电磁场分量表达式的基础上,利用螺旋带的边界条件,导出了等离子填充带状螺旋线中电磁波传播的色散方程.
A tape helix show wave structure is filled with uniform plasma. A dielectric is loaded inside the region between helix and a conducting waveguide. The system is immersed in a strong longitudinal magnetic field. By means of helix tape model and linear field theory, the field equations and the boundary conditions in plasma region and dielectric region are given. On the basis of the field analysis, the dispersion relation of the slow wave structure is derived and some discussions are given.
