# Poynting's theorem and energy conservation in the propagation of light in bounded media

@article{Richter2007PoyntingsTA, title={Poynting's theorem and energy conservation in the propagation of light in bounded media}, author={Felix Richter and Matthias Florian and Klaus Henneberger}, journal={EPL (Europhysics Letters)}, year={2007}, volume={81}, pages={67005} }

Starting from the Maxwell-Lorentz equations, Poyntings theorem is reconsidered. The electromagnetic energy flux vector is introduced such that it can be related to the kinetic energy of the matter subsystem. Conservation of the total energy follows. In our discussion, the microscopic nature of media is represented exactly by susceptibility functions, which do not necessarily have to be known. On this footing, it can be shown that energy conservation in the propagation of light through bounded…

It is argued that the second law of thermodynamics requires that the volume contribution be positive and that this requirement, in turn, prohibits negative refraction and holds for active or passive media and in the presence of anisotropy and spatial dispersion.
