Bandwidth constraints for passive superluminal propagation through metamaterials

Gustafsson, Mats LU orcid (2012) In Applied Physics A: Materials Science & Processing 109(4). p.1015-1021
Abstract
Superluminal transmission of electromagnetic waves is usually observed in a narrow bandwidth range and the velocity outside this range is subluminal. In this paper, it is shown that the transmission coefficient for superluminal propagation through a periodic metamaterial structure satisfies a sum rule. The sum rule and its corresponding physical bound relate frequency regions with a phase velocity above an arbitrary threshold with the thickness of the slab. The theoretical results are illustrated with numerical examples.
