To cite this article: O.B. Vorobyev (2015): Continuity equation for momentum of the electromagnetic wave in a lossy dispersive magnetoelectric medium, Journal of Modern Optics, Continuity equation for the canonical pseudomomentum density in a magnetoelectric medium with dispersive losses is examined using consistent microscopic description of the electromagnetic wave energy. Accordingly, the canonical pseudomomentum is presented by the kinetic momentum of the electromagnetic field and pseudomomentum of oscillating bound charges, which is identified as a combination of the medium and electromagnetic pseudomomenta in contrast with previous quasi-static approaches. The ponderomotive and reaction forces are defined by the time derivatives of the medium and electromagnetic pseudomomenta, which depend on the "hidden momentum" in the case of a magnetoelectric medium. Properties of medium-field interaction are connected with translational invariance of the pseudomomentum in relation to a homogeneous lossless medium. Transport of the canonical pseudomomentum is explained by the kinetic momentum flux corresponding to the energy flux as well as translational invariance of the pseudomomentum, which are illustrated using the relativistic and effective mass densities of the electromagnetic wave. The optical pseudomomentum of the electromagnetic wave is defined in accordance with conducted analysis of energy and momentum transport while fallacies of approaches based on the Abraham, Minkowski, and total momenta are specified. Structure of the full momentum density of a closed medium-field system comprised of the densities of the optical pseudomomentum of the electromagnetic wave as well as the mechanical momentum and pseudomomentum of a host medium is expounded using description of medium-field interaction.

The processes of storage and dissipation of electromagnetic energy in nanostructures depend on both the material properties and the geometry. In this paper, the distributions of local energy density and power dissipation in nanogratings are investigated using the rigorous coupled-wave analysis. It is demonstrated that the enhancement of absorption is accompanied by the enhancement of energy storage both for material at the resonance of its dielectric function described by the classical Lorentz oscillator and for nanostructures at the resonance induced by its geometric arrangement. The appearance of strong local electric field in nanogratings at the geometry-induced resonance is directly related to the maximum electric energy storage. Analysis of the local energy storage and dissipation can also help gain a better understanding of the global energy storage and dissipation in nanostructures for photovoltaic and heat transfer applications.
