Baseband and Envelope Propagation in Media Modeled by a Class of Complex Dispersion Relations
Journal of the Optical Society of America B
We demonstrate that a class of simplified complex dispersion relations, which obey causality, can model baseband and envelope propagation in conventional and negative index materials. One such dispersion relation is a special case of the Drude model; another yields the Kuramoto–Shivashinsky equation; a third, in the limit, yields the simplest dispersion for negative index materials.
