on a period cell, any good way to do it?
The prolem is that the field scales with 1/r^3, thus not converge in 3-D, so
cannot use cut off. On the other hand, the Maxwell's equation on a period cell
is well defined, thus the solution should exist. So have to use Fourier
transformation to solve it, but for NxN cell with period BC, the computation
is simple hopeless when N is large...
