Abstract
Recently, superluminal velocities have been reported for the propagation of localized microwave pulses. A critical interpretation based on the analysi s of plane and spherical waves shows that the superluminal effects are caus ed by interference phenomena. We demonstrate that Bessel beams or X-waves a re unsuitable for superluminal signal transfer. (C) 2001 Elsevier Science B .V. All rights reserved.
