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… 

Electromagnetic-Energy Flow in Anisotropic Metamaterials: The Proper Choice of Poynting’s Vector

We study the controversy about the proper determination of the electromagnetic energy-flux field in anisotropic materials, which has been revived due to the relatively recent experiments on negative

Correct definition of the Poynting vector in electrically and magnetically polarizable medium reveals that negative refraction is impossible.

TLDR
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.

The Generalized Poynting Theorem for the General Field and Solution of the 4/3 Problem

The generalized Poynting theorem is applied to the equilibrium system of particles, both inside and outside the system. The particles are bound to each other by means of the electromagnetic and

The photon Green's function for bounded media: Splitting property and nonequilibrium radiation laws

The presence of a medium boundary has been a major obstacle for the theoretical description of the propagation, emission and absorption of light due to the loss of translational invariance. We

Generalized radiation law for excited media in a nonequilibrium steady state

We consider the interacting system of light and matter and present quantum-kinetically exact relations for the propagation of light through arbitrarily absorbing and dispersive steadily excited media

Radiative transfer and flux theory

The fundamental phenomenological equations of radiative transfer, e.g., Lambert’s cosine rule and the radiant transport equation, are derived from an analysis based on the Cauchy flux theory of

Generalizing Planck's law: Nonequilibrium emission of excited media

Using a quantum‐kinetic many‐body approach, exact results for the interacting system of field and matter in a specified geometry are presented. It is shown that both the spectral function of photons

The Murad-Brandenburg Poynting Field Conservation Equation and Possible Gravity Law

A corollary states that in the beginning, the ‘Big Bang’ theory exists only with one separate kind of force that suddenly evolved into gravity, nearand far-distance nuclear, electromagnetic forces.

A Poynting vector/field conservation equation and gravity-The Murad-Brandenburg equation

A corollary of the ‘Big Bang’ theory is that in the beginning, there was only one separate kind of force that suddenly evolved into gravity, nuclear, electric and magnetic forces. Is it
