Superluminal speed of information? (reply)
Stenner et al. reply — It was most natural to present our findings1 in the time domain, although there is an equivalent explanation in the frequency domain if Fourier analysis is used. Nimtz2 uses a frequency-dom...

The speed of information in a ‘fast-light’ optical medium
One consequence of the special theory of relativity is that no signal can cause an effect outside the source light cone, the space-time surface on which light rays emanate from the source1. Violation of this prin...
