论文摘要
我们研究电磁场非线性的一些观察性特征。首先，我们显示了非线性在用$（\ varepsilon> 0，μ<0）$触发真空的材料行为方面所起的至关重要的作用，该行为对应于铁磁物质。其次，考虑非线性引起的介电常数和敏感性，以通过对数电动力学的分散关系获得折射率。最后，我们考虑了由移动的带电粒子与以电磁场非线性为特征的介质产生的电磁辐射。为此，我们考虑对数电动力学。结果表明，辐射是由粒子像Cherenkov效应中发生的介质一样驱动的。
We study some observational signatures of nonlinearities of the electromagnetic field. First to all we show the vital role played by nonlinearities in triggering a material behavior of the vacuum with $(\varepsilon > 0, μ<0)$, which corresponds to a ferrimagnetic material. Secondly, the permittivity and susceptibility induced by nonlinearities are considered in order to obtain the refractive index via the dispersion relation for logarithmic electrodynamics. Finally, we consider the electromagnetic radiation produced by a moving charged particle interacting with a medium characterized by nonlinearities of the electromagnetic field. To this end we consider logarithmic electrodynamics. The result shows that the radiation is driven by the medium through which the particle travels like the one that happens in the Cherenkov effect.
