研究了发散和会聚磁场配置下平面螺旋天线产生的有界等离子体（圆柱形，大直径为45 cm）中射频（RF）波的传播。根据螺旋波的特性，对所测得的激励磁场的幅值和相位进行了检验，并与基于有限元法的托卡马克输运分析系统（tokamK/Wave）的计算结果进行了比较。在发散（收敛）场中，波的传播区域随着离天线的距离的增加而在径向上变宽（聚焦）。
Radio frequency (RF) wave propagation in a bounded plasma (cylindrical shape with a large diameter of 45 cm) produced by a planar, spiral antenna was investigated under divergent and convergent magnetic field configurations. The measured excited magnetic field amplitude and the phase were examined based on helicon wave characteristics, and were consistent with the computed results using the Transport Analyzing System for tokamaK/Wave analysis by Finite element method (TASK/WF) code. The wave propagation region was broadened (focused) in the radial direction with increasing distance from the antenna under the divergent (convergent) field.
