Poynting's Vector: Comments on a Recent Paper by Clark Jeffries

Poynting's theorem, and the use of Poynting's vector to express the transfer of energy from one part of a system to another in terms of the electric field E and the magnetic field H are shown to follow directly from Maxwell's equations and to be as applicable to steady state situation...

Description
Summary:Poynting's theorem, and the use of Poynting's vector to express the transfer of energy from one part of a system to another in terms of the electric field E and the magnetic field H are shown to follow directly from Maxwell's equations and to be as applicable to steady state situations (such as a lamp connected to a battery) as to radiation.
