Phys. Rev. A 65, 052124 (2002) [5 pages]Superoscillations and tunneling timesReceived 17 October 2001; published 17 May 2002 It is proposed that superoscillations play an important role in the interferences that give rise to superluminal effects. To exemplify that, we consider a toy model that a wave packet to travel in zero time and negligible distortion, a distance arbitrarily larger than the width of the wave packet. The peak is shown to result from a superoscillatory superposition at the tail. Similar reasoning applies to the dwell time. © 2002 The American Physical Society URL:
