Title: Superposition Principle And The Problem Of Additivity Of The Energies And Momenta Of Distinct Electromagnetic Fields
Author: Notte-Cuello E.A.
Rodrigues Jr. W.A.
Abstract: In this paper we prove in a rigorous mathematical way (using the Clifford bundle formalism) that the energies and momenta of two distinct and arbitrary free Maxwell fields (of finite energies and momenta) that are superposed are additive and thus that there is no incompatibility between the principle of superposition of fields and the principle of energy-momentum conservation, contrary to some recent claims. Our proof depends on a noticeable formula for the energy-momentum densities, namely, Riesz formula {black star}τa = 1/2 Fθa{star operator} Ta = frac(1, 2) F θa over(F, ̃), which is valid for any electromagnetic field configuration F, in particular the one satisfying the free Maxwell equation ∂ F= 0. © 2008 Polish Scientific Publishers PWN, Warszawa.
