| 摘 要： | 将等离子体填充的螺旋线慢波结构置于一纵向有限磁场中,考虑到磁化等离子体和介质的作用,该系统沿径向分为两个区域.采用螺旋导电面模型,利用已导出的慢波结构色散方程,数值计算了在不同的等离子体密度和磁场强度条件下,螺旋线慢波结构的色散特性,并对数值计算的结果进行了详细的分析.

| Abstract: | A helical slow wave structure filled with plasma is located in a finite longitudinal magnetic field.Taking the effect of the magnetized plasma and the dielectric into account,the system is radially separated into two regions.By means of conducting plane model and Maxwell equation,the distribution of the electromagnetic field is established.Using the boundary conditions of each region,the dispersion relation of the slow wave structure is derived.The dispersion characteristics are analyzed by numerical comput... |
