Abstract
Poynting
theorem plays a very important role in analyzing electromagnetic phenomena. The
electromagnetic power flux density is usually expressed with the Poynting vector.
However, since Poynting theorem basically focuses on the power balance in a
system, it is not so convenient in some situations to use it for evaluating the
electromagnetic energies. The energy balance issue for time varying fields is
revisited in this paper, and a set of energy balance equations are introduced,
and a modified method for evaluating power flux is proposed.
