Abstract
Electromagnetic radiation is strongly influenced by structure in the permittivity and permeability. Structures modulated in space and time can appear to move with speeds at or above the speed of light and produce remarkable effects of increasing interest theoretically spurred by the possibility of experimental realization. We take theory into the quantum domain identifying singularities in transluminal structures analogous to the Schwarzschild singularity in the gravitational metric of a black hole. We show that these singularities will spontaneously radiate photon pairs, analogous to Hawking radiation. A temperature can be associated with the radiation which depends exponentially on the length of time for which the structure in is motion. In addition to spontaneous radiation, stimulated emission is produced by incident radiation.
