假设几何光学,研究了在三维环形等离子体中传播的电磁波(O 模式和 X 模式)和电子伯恩斯坦波(B 模式)的波轨迹和回旋阻尼。通过注入 O 模式和 X 模式的电子回旋加热 (ECH) 在低密度中非常有效 (\(\omega_{\text{pe}}{ }\varOmega_{\text{e}}{\approx}\omega\)),其中 B 模式从 X 模式或 O 模式线性转换(后者先转换为 X 模式,然后转换为 B 模式)。由于阻尼强,B 模式对于低 T e 等离子体也很有用。详细研究了这些高密度等离子体中的传播特性和模式转换。
Wave trajectories and cyclotron damping of the electromagnetic waves (O- and X-modes) and the electron Bernstein wave (B-mode) propagating in three dimensional toroidal plasmas are investigated, assuming the geometrical optics. Electron cyclotron heating (ECH) by injection of O- and X-mode is effective in low density (\(\omega_{\text{pe}}{ }\varOmega_{\text{e}}{\approx}\omega\)), where B-mode is linearly converted from X-mode or O-mode (the latter being converted to X- and then to B-mode). Because of strong damping, B-mode is also useful for low T e plasmas. Propagation characteristics and mode-conversion in these high density plasmas are studied in detail.
