采用等离子体平板模型和三维天线模型研究JET装置中离子回旋频段的天线与等离子体的耦合过程,在离子回旋波被等离子体全部吸收的假设条件下,通过数值求解等离子体中的快磁声波方程,得到天线耦合到等离子体的总功率随天线到外金属壁的距离的增加而增加。

英文摘要：

The coupling of the ICRF antennas to the plasma in JET was studied by employing a plasma slab model and a 3-D antenna model.Through using a hypothesis that all the ion cyclotron waves which reaches the plasma bulk is completely absorbed,the fast magnetosonic waves equations were numerically resolved.The results showed that the increase in the distance between the antennas and outer metal wall corresponds to the increase in the coupled total power of the antenna-plasma.
