Electromagnetic fieldsMomentumDielectricsLinear systemsEnergyThe total momentum of a thermodynamically closed system is unique, as is the total energy. Nevertheless, there is continuing confusion concerning the correct form of the momentum and the energy-momentum tensor for an electromagnetic field ...
Using certain suitable transformations, tensor calculus permits one to establish an expression of the energy-momentum tensor, also called the energy quantity of motion tensor, for domains submitted to an electromagnetic field in various interesting cases in the theory of relativity, which have not ...

Classical relativistic field theory is used as a basis for a general discussion of the problem of splitting up the total energy–momentum tensor of a system into contributions from its component subsystems. Both the Minkowski and Abraham forms (including electrostriction) arise naturally in alternati...
//In this part we discuss how energy and momentum is stored in EM field, making sure that momentum & energy conservation is always right. //Throughout this article EM refers to "Electromagnetic" or "Electromagnetism". We know that conservation of energy and momentum are part of the basic ...

Energy–Momentum Tensors for Dispersive Electromagnetic Waves Classical relativistic field theory is used as a basis for a general discussion of the problem of splitting up the total energy–momentum tensor of a system into contributions from its component subsystems. Both the Minkowski and Abraham.....
A symmetric and conserved energy-momentum tensor for a scalar field in a moving medium is derived using the Gordon metric. When applied to an electromagnetic field, the method gives a similar result. This approach thus points a way out of the old Abraham-Minkowski controversy about the correct...

The energy-momentum tensor is derived for a plane quasimonochromatic wave packet of an electromagnetic wave in cold collisionless non-magnetized plasma. A comparison with previous results indicates the relevance of the nonlinear motion in the direction of wave propagation....
