Superluminal Propagation > s.a. causality violations; electromagnetism; information; light; photons; tachyons.
* Experiment: Superluminal group velocities seen by various labs working on evanescent electromagnetic waves (1993–1994); 2002, Pulses sent over a significant distance in a 120-m cable made from a coaxial 'photonic crystal'.
* Other possibilities: Quantum tunneling (e.g., photons); Ultrasound in water with plastic beads; Tachyons.
* Theory: In connection with possible causality violations, the relevant velocity is the front velocity, which coincides with the one given by the characteristics of the pde governing wave propagation [for a large class of equations, @ see refs in Shore NPB(02)gq].
