The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Energy flow and forces in multi-layer dielectric structuresFrias, Winston Enrique 12 January 2011
The propagation of electromagnetic waves through media with dispersive dielectric permittivity. It is shown that under resonant conditions the energy velocity is always subluminal. The energy velocity is different from the group velocity and the delay velocity. The momentum conservation equation with the Lorentz force is derived from macroscopic and microscopic analysis. The relations of the forces on the dielectric with momentum and pseudomomentum of the electromagnetic field are clarified.
