[UNESP]2022-04-282022-04-282003-01-01Physical Review D, v. 68, n. 6, 2003.0556-2821http://hdl.handle.net/11449/224370We study the optical paths of the light rays propagating inside a nonlinear moving dielectric medium. For rapidly moving dielectrics we show the existence of a distinguished surface which resembles, as far as the light propagation is concerned, the event horizon of a black hole. Our analysis clarifies the physical conditions under which electromagnetic analogues of gravitational black holes can eventually be obtained in laboratory. © 2003 The American Physical Society.engArtigo10.1103/PhysRevD.68.0615022-s2.0-0142219756
