Thus we conclude that the expression for the electromagnetic energy-momentum tensor (8) should be valid in far zone and does not imply any changes in the formulation of the standard Poynting theorem. As a consequence both bound and radiative EM field components should have the same propagation (or retardation) rates determined by the velocity of light c.

Evans1 Alpha Institute for Advanced Studies (www.aias.us) The deflection of light by gravitation is explained using the Poynting theorem Complex Poynting's Theorem. For systems in the sinusoidal steady state, a useful alternative to the form of Poynting's theorem introduced in Secs. 11.1 and 11.2 results from writing Maxwell's equations in terms of complex amplitudes before they are combined to provide the desired theorem.

10.2 Complex Poynting’s Theorem and Lossless Condi-tions 10.2.1 Complex Poynting’s Theorem Poynting vector is also called as instantaneous energy flux density. Here rate of energy transfer P is perpendicular to both E and H .

CONCLUSION Poynting’s theorem has been successfully applied to the case of the homopolar generator (as well as its linear analog), in which a current ﬂows in a circuit due to the motion of a conductor through a uniform background magnetic ﬁeld. The power generated derives from the magnetic braking deceler- ation of the rotating Faraday disk.

The complex Poynting theorem has been used to study power flow and energy storage for the case in which a plane wave (polarization wherein the electric field is in the plane of incidence) is scattered from a generally lossy, anisotropic, non-Hermitian diffraction grating. The full electromagnetic fields of the diffraction grating system were specified, and, in applying the complex Poynting Here is a version of Poynting's theorem, appropriate for media with ϵr=1, μr=1 ( for simplicity). ∇⋅S+12∂∂t(ϵ0E2+B2μ0)+E⋅J=0,. where S is the Poynting Use Poynting's theorem to determine the direction and magnitude of power flow in an electromagnetic system.
