Is The FDTD solver an implicit or explicit time stepping scheme?

I think it is an implicit method but you may refer to Wikipedia http://en.wikipedia.org/wiki/FDTD to find an exact answer.

What FDTD does is it calculates the new magnetic field from old mag. and electric fields and then a new electric field from the old mag. and elec. fields over time.
Thereby moving forward time-step after time-step.
