Microwave experiments carried out by Nimtz and Enders [1] showed, that under special circumstances, the propagation time through an undersized wave guide is independent of its length. Thus superluminal signal transport cannot be ruled out in principle. Nevertheless it was shown [2], that these results are in accordance with Einstein causality, and strictly time bounded signals propagate not faster than light. Here the propagation of different kinds of wave packets is simulated, and it clearly can be seen, that superluminal signal transport is possible under special circumstances Department of Physics, Faculty of Science, Ubon Ratchathani University, Ubon Ratchathani, 34190, Thailand Received December 26, 1995
