Popis:	An exact separation of both electric and magnetic energies into stored and lost energies is shown to be possible in the special case when the wave impedance is independent of frequency. Using an example metamaterial response that provides a negative refractive index, it is shown that negative time-averaged stored energy can occur, with total energy that remains positive.
