摘要：

It is well established that the group velocity of wave propagation can exceed the vacuum speed of light. However, in such cases the group velocity cannot be interpreted as a velocity of information transfer. The phenomenon essentially consists in an analytic continuation of the pulse shape available within the light cone.
