  A near-field analysis based on Maxwells equations is presented which
indicates that the fields generated by both an electric and a magnetic dipole
or quadrapole, and also the gravitational waves generated by a quadrapole mass
source propagate superluminally in the nearfield of the source and reduce to
the speed of light as the waves propagate into the farfield. Both the phase
speed and the group speed are shown to be superluminal in the nearfield of
these systems. Although the information speed is shown to differ from group
speed in the nearfield of these systems, provided the noise of the signal is
small and the modulation method is known, the information can be extracted in a
time period much smaller than the wave propagation time, thereby making the
information speed only slightly less than the superluminal group speed. It is
shown that relativity theory indicates that these superluminal signals can be
reflected off of a moving frame causing the information to arrive before the
signal was transmitted (i.e. backward in time). It is unknown if these signals
can be used to change the past.
