Superluminal signals: an engineer’s perspective
نویسنده
چکیده
Recent experiments with evanescent waveguide modes demonstrated the existence of superluminal group velocities. The still ongoing debate concerning the definition of an appropriate signal velocity is revisited, and a case study of a raised cosine signal is presented to investigate the practical relevance of superluminal signals. 2001 Elsevier Science B.V.

Basics of superluminal signals
The paper elucidates the physical basis of experimental results on superluminal signal velocity. It will be made plausible that superluminal signals do not violate the principle of causality but they can shorten the vacuum time span between cause and effect. The causal behaviour is based on the property that a physical signal has a finite duration as a result of its frequency band limitation.
متن کاملSuperluminal Signal Velocity
It recently has been demonstrated that signals conveyed by evanescent modes can travel faster than light. In this report some special features of signals are introduced and investigated, for instance the fundamental property that signals are frequency band limited. Evanescent modes are characterized by extraordinary properties: Their energy is negative, they are not directly measurable, and the...

We introduce a simple method to illustrate how the Lorentz transformation lead to causal loop paradoxes when they are applied to superluminal velocities. c © Electronic Journal of Theoretical Physics. All rights reserved.
متن کاملAbout Superluminal Propagation of an Electromagnetic Wavepacket Inside a Rectangular Waveguide
We discuss the propagation of an electromagnetic wavepacket inside a rectangular waveguide, of the type employed in recent experiments on superluminal tunneling of electromagnetic signals. By exploiting the analogy between particle and photon tunneling, we consider both evanescent and growing waves inside the narrowed part of the waveguide. The Fourier expansion of such waves shows that the bar...
