  In this paper the fields generated by an electric dipole and a gravitational
quadrapole are shown to propagate superluminally in the nearfield of the source
and reduce to the speed of light as the fields propagate into the farfield. A
theoretical derivation of the generated fields using Maxwell's equations is
presented followed by a theoretical analysis of the phase and group speed of
the propagating fields. This theoretical prediction is then verified by a
numerical simulation which demonstrates the superluminal propagation of
modulated signals in the nearfield of their sources. An experiment using simple
dipole antennas is also presented which verifies the theoretically expected
superluminal propagation of transverse electromagnetic fields in the nearfield
of the source. The phase speed, group speed, and information speed of these
systems are compared and shown to differ. Provided the noise of a signal is
small and the modulation method is known, it is shown that the information
speed can be approximately the same as the superluminal group speed. According
to relativity theory, it is known that between moving reference frames,
superluminal signals can propagate backwards in time enabling violations of
causality. Several explanations are presented which may resolve this dilemma.
