The starting point is dimension-3 MCFJ electrodynamics in matter whose modified Maxwell equations, permittivity tensor, and dispersion relations are recapitulated. Corresponding refractive indices are achieved in terms of the frequency and the vector-valued background field. For a purely timelike background, the refractive indices are real. Their associated propagation modes are circularly polarized and exhibit birefring","authors_text":"Let\\'icia Lisboa-Santos, Manoel M. Ferreira Jr., Marco Schreck, Pedro D. S.
