We considered two cases (i) medium consists of lossy metallic nanostructures embedded into a gain material and (ii) the gain material is embedded directly into the nanostructures. We found the shape and velocity of an optical pulse coupled with the polarization wave.","authors_text":"Andrei I. Maimistov, Bridget Kennedy, Ildar R.
