Phys. Rev. D 65, 064027 (2002) [6 pages]Analogue gravity from electrodynamics in nonlinear mediaReceived 27 June 2001; published 28 February 2002 Working with electrodynamics in the geometrical optics approximation we derive an expression representing effectively curved geometries which guide the propagation of electromagnetic waves in material media whose physical properties depend on an external electric field. The issue of birefringence is addressed, and the trajectory of the extraordinary ray is explicitly worked out. Quite general curves are obtained for the path of the light ray by suitably setting the electric field. © 2002 The American Physical Society URL:
