| 中文摘要: |
| 采用平板等离子体模型结合三维天线模型研究了托卡马克装置中离子回旋频段的天线与等离子体的耦合问题,考虑等离子体中传播的快磁声被全部吸收, 通过数值求解快磁声波方程，得到天线耦合功率谱和耦合电阻，发现不同谱分量的偶合功率有很大差别，天线的耦合效率主要取决于天线的机制及等离子体参数. |
| 英文摘要: |
| The coupling of an ICRF antenna to the plasma in the Tokamak is investigated by employing a slab geometry model combining with a 3-D antenna model. The power spectra and the coupling resistance of the antenna are obtained by numerically resolving the fast magnetosonic waves equations on the condition that fast magnetosonic waves are absorbed completely in the plasma. It shows that great differences exist in the radiation power of different spectra, and that the coupling efficiency of antenna is determined by its mechanism and the parameters of the plasma. |
