Abstract
The dynamical Casimir effect in quantum electrodynamics, which occurs for a frequency-modulated electromagnetic oscillator, is described in terms of reflection backward in time of the oscillator mode. From an e xperimental viewpoint, backward-in-time reflections appear as radiated photons. The distribution of the electromagnetic radiation due to a m odulation pulse is computed as a function of the frequency omega and i s shown to exhbit a (1/omega) singularity in the limit omega --> 0.
