标题： Modified plasma waves described by a logarithmic electrodynamics

摘要： 等离子体波在一种新的非线性对数电动力学模型中的传播被进行了研究。 应用了一个冷、均匀、无碰撞的流体等离子体模型。 磁化等离子体中的静电波被证明对应于修改后的Trivelpiece-Gould模态，同时等离子体频率和上混合频率发生变化，这些变化是由对数电动力学效应驱动的。 电磁波由广义的Appleton-Hartree色散关系描述。 详细分析了沿平衡磁场方向或垂直方向传播的情况。 特别是得到了广义的普通模态和非常规模态。 我们确定了由于对数电动力学引起的新型非常规模态的允许和禁止频率带的变化。 提供了关于环境磁场强度的估计，以使非线性电动力学效应变得决定性。 显示英文摘要

摘要： The propagation of plasma waves in a new non-linear, logarithmic electrodynamics model is performed. A cold, uniform, collisionless fluid plasma model is applied. Electrostatic waves in magnetized plasma are shown to correspond to modified Trivelpiece-Gould modes, together with changes of the plasma and upper-hybrid frequencies, driven by the logarithmic electrodynamics effects. Electromagnetic waves are described by a generalized Appleton-Hartree dispersion relation. The cases of propagation parallel or perpendicular to the equilibrium magnetic field are analyzed in detail. In particular, generalized ordinary and extraordinary modes are obtained. We determine the changes, due to logarithmic electrodynamics, in the allowable and forbidden frequency bands of the new extraordinary mode. Estimates are provided about the strength of the ambient magnetic field, so that the non-linear electrodynamics effects become decisive.
