First, for computing decay rates, you are better off using harminv than printing out field energies and trying to fit them somehow. Second, the result looks perfectly stable to me; if it were unstable it would be blowing up. What you mean is that the field energy is oscilating, which just means that not all of the energy is contained within the box you defined. If you output a picture of the fields or the field energy, this will probably be obvious. (In general, outputting a few pictures is always a good idea to make sure things are behaving the way you think.) Regards, Steven G.
