Numerical issues

To have an efficient code a Yee method [Yee66] is used in [ZAG95]. Its main feature are staggered grids in space and time for E and B. The splitting scheme for the Bloch equation is compatible with these advantages (much more than the Crank–Nicolson scheme) if the grid for the discretization of the Bloch equation is acurately chosen [Bid03]. The numerical methodwhich is obtained is explicit and highly parallelizable.
