本文对弱相对论性麦克斯韦等离子体中有限密度的电子回旋频率及其谐波附近的电磁波在静磁场中的斜向和垂直传播的吸收理论进行了全面的综述。特别强调的是在吸收过程中所涉及的物理，而不是在公式的详细推导。的吸收系数的能量平衡的基础上进行评估，显示有限的等离子体密度相关的极化效应的意义。此外，托卡马克等离子体的光学厚度的两个基本模式的各种谐波给出和相应的缩放等离子体参数和磁场进行了检查。
A comprehensive overview of the theory of the absorption of electromagnetic waves around the electron cyclotron frequency and its harmonics in a weakly relativistic Maxwellian plasma of finite density is given for propagation both oblique and perpendicular with respect to a static magnetic field. Particular stress is laid on the physics involved in the absorption process rather than on the detailed derivation of the formulae. The absorption coefficient is evaluated on the basis of the energy balance which displays the significance of polarization effects related to finite plasma density. Furthermore, the optical thickness of a Tokamak plasma for the various harmonics of the two fundamental modes is given and the corresponding scaling with respect to the plasma parameters and magnetic field is examined.
