  We consider a gravitational wave of arbitrary frequency incident on a normal
or a super-conductor. The gravitationally induced fields inside the conductor
are derived. The outward propagating EM waves are calculated for a low
frequency wave on a small sphere and for a high frequency wave incident on a
large disk. We estimate for both targets the GW to EM conversion efficiencies
and also the magnitude of the superconductor's phase perturbation.
