Maxwell’s equations are supplemented with a term that takes into account the presence of polymers in the medium. The dependence of the spatial-energy characteristics of the optical pulse on the polymer concentration is revealed.</p></abstract><trans-abstract xml:lang="ru"><p>В настоящей работе исследуется динамика электромагнитного излучения в тонкой полимерной пленкой, содержащей углеродные нанотрубки.
