Stimulated Hawking emission from electromagnetic analogue black hole: Theory and observation
Physical Review D
In this paper we consider possible analogue Hawking radiation from a normal dielectric and metamaterial composite, having an analogue horizon where the dielectric parameters vanish and change sign upon crossing this transition zone. We follow a complex path analysis to show the presence of an analogue Hawking temperature at the horizon and subsequent photon production from the ambient electromagnetic field. The possibility of experimental observation is also commented upon.
