径向边界条件引起的电子回旋波极化反转

Polarization reversal of electron cyclotron wave due to radial boundary condition

Kazunori Takahashi, Toshiro Kaneko, Rikizo Hatakeyama

摘要:

实验和理论研究了具有真空层的非均匀磁化等离子体柱在选择性发射左手极化波(LHPW)时,电子回旋共振(ECR)频率的电磁波的传播和吸收.从LHPW到右旋极化波的极化反转被发现发生在ECR点附近。其结果是,明确了被认为在ECR点处不被吸收的LHPW在ECR点附近被吸收。这种现象可以通过考虑径向边界条件的影响来解释。此外,还发现极化反转点可以通过外部参数如等离子体半径来调节。

英文摘要:

Propagation and absorption of electromagnetic waves with electron cyclotron resonance (ECR) frequency are experimentally and theoretically investigated for the case of inhomogeneously magnetized plasma column with peripheral vacuum layer, when a left-hand polarized wave (LHPW) is selectively launched. The polarization reversal from the LHPW to the right-hand polarized wave is found to occur near the ECR point. As a result, it is clarified that the LHPW, which has been considered not to be absorbed at the ECR point, is absorbed near the ECR point. The phenomena can be explained by taking into account the effects of the radial boundary conditions. In addition, it is found that the polarization reversal point can be adjusted by the external parameters, for example, plasma radius.
