Ray-tracing through EC resonance and the wave energy flux

E Westerhof, M.D Tokman, M.A Gavrilova2001年Fusion Engineering and DesignIF 1.7出版社

AbstractA paradox in the theory of wave propagation through electron cyclotron (EC) resonance is noted: absorption is weak as required for the validity of WKB theory or geometric optics, yet the wave power flux given by the theory is in clear disagreement with the predicted ray-trajectories. The paradox is traced to the large anti-Hermitian parts of the dielectric tensor near resonance. The latter are shown to modify the wave power flux. The modified flux is in agreement with the ray-trajectories.

電子サイクロトロン(EC)共鳴を介した波動伝搬の理論にはパラドックスがあることが指摘されている。すなわち、WKB理論や幾何光学の妥当性に必要な吸収は弱いにもかかわらず、理論によって与えられる波動パワー束は、予測される光線軌道と明らかに矛盾する。このパラドックスは、共鳴近傍における誘電テンソルの大きな反エルミート部分に起因する。後者は波動パワー束を修正することが示される。修正されたフラックスは光線軌道と一致する。
