RESUMO
Classical electrodynamics is a powerful tool to address optical effects of continuous media. In this talk we use the electromagnetism
framework to describe the optics of unusual matter. We begin revising basic aspects of electromagnetic wave propagation in
continuous media, including constitutive relations, anisotropy and crystal birefringence. In this sense, we introduce the Maxwell-
Carroll-Field-Jackiw (MCFJ) electrodynamics, a Lorentz-violating theory in vacuum, which in matter is concerned with relevant material properties, as the Chiral Magnetic Effect (CME), associated with a macroscopic magnetic current. The MCFJ model is also connected with the anomalous Hall effect and with the description of chiral media and systems for detection of cold axions. For a purely timelike background the refractive indices are real, having associated circularly polarized modes that imply birefringence expressed in terms of the rotatory power. One of the interesting properties of the MCFJ model is that the timelike background plays the role of the magnetic conductivity, opening the connection with the CME. We then show how the electrodynamics formalism can be properly used to examine optical properties of a dielectric medium supporting magnetic current. The same method may be employed to
examine the behavior of bi-isotropic and bi-anisotropic matter and chiral cold plasmas. These examples illustrate a fruitful interplay
between classical electrodynamics and optical matter characterization that could be worthy for the part of the field theory community
which has modified electrodynamics as an active line of research.
