Abstract
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 (ε > 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.
