On the possibility of superluminal energy propagation in a hyperbolic metamaterial of metal-dielectric layers

open access: yes, 2017
The energy propagation of electromagnetic fields in the effective medium of a one-dimensional photonic crystal consisting of dielectric and metallic layers is investigated. We show that the medium behaves like Drude and Lorentz medium, respectively, when
