共振区在地球的偶极子磁层确定为电子回旋共振与倾斜传播的非常低的频率合唱，极低频率的嘶嘶声，电磁离子回旋，和磁声波。在（L，λ）空间（L为磁壳层，λ为磁纬）中给出的共振区取决于等离子体内外的粒子密度分布、特定波段和电子动能。这项工作是Ni和Summers [Phys. Plasmas 17，042902（2010）]的姊妹论文，它考虑了严格的场对准波传播。包括波法线角参数增加了一个额外的自由度的计算，并强调需要全球观测数据的波谱特性。共振区与全球波分布的比较有助于辐射带电子动力学的模拟。共振区也是潜在的使用在解释的…
Resonance zones in the Earth’s dipole magnetosphere are determined for electron cyclotron resonance with obliquely propagating very-low-frequency chorus, extremely-low-frequency hiss, electromagnetic ion cyclotron, and magnetosonic waves. The resonance zones, which are presented in (L,λ) space, where L is magnetic shell and λ is magnetic latitude, depend on the assumed particle density distributions inside and outside the plasmasphere, the specified wave bands, and the electron kinetic energy. This work is a companion paper of Ni and Summers [Phys. Plasmas 17, 042902 (2010)], which considers strictly field-aligned wave propagation. Inclusion of the wave normal angle parameter adds an extra degree of freedom to the calculations, and emphasizes the need for global observational data on the wave spectral properties. Comparison of resonance zones with global wave distributions is a useful aid in the modeling of radiation belt electron dynamics. Resonance zones are also of potential use in the interpretation o...
