低杂波（LH）波（Ωci <$ω <$Ωce，其中Ωi，e <$Zi，eeB/mi，ec）具有经由相对快的尾电子上的电子朗道共振强烈阻尼的吸引力性质，因此非常适合于驱动电流。已建立的建模技术使用具有自洽非麦克斯韦分布的Wentzel-Kramers-Brillouin（WKB）展开。高阶WKB展开对平行波数的演化和衍射阻尼有一定的影响。Perevezev，Nucl. Fusion 32，1091（1991）]。已经开发了在LH频率范围内有效的TORIC全波电磁场求解器的大规模并行版本[J.C. Wright等人，Comm.Comp.Phys.4，545（2008）]并耦合到电子Fokker-Planck解算器CQL 3D [R. W.哈维和M.

Lower hybrid (LH) waves (Ωci⪡ω⪡Ωce, where Ωi,e≡Zi,eeB/mi,ec) have the attractive property of damping strongly via electron Landau resonance on relatively fast tail electrons and consequently are well-suited to driving current. Established modeling techniques use Wentzel–Kramers–Brillouin (WKB) expansions with self-consistent non-Maxwellian distributions. Higher order WKB expansions have shown some effects on the parallel wave number evolution and consequently on the damping due to diffraction [G. Pereverzev, Nucl. Fusion 32, 1091 (1991)]. A massively parallel version of the TORIC full wave electromagnetic field solver valid in the LH range of frequencies has been developed [J. C. Wright et al., Comm. Comp. Phys. 4, 545 (2008)] and coupled to an electron Fokker–Planck solver CQL3D [R. W. Harvey and M. G. McCoy, in Proceedings of the IAEA Technical Committee Meeting, Montreal, 1992 (IAEA Institute of Physics Publishing, Vienna, 1993), USDOC/NTIS Document No. DE93002962, pp. 489–526] in order to self-consist...
