Abstract: In this paper, we study the evolution of a short-duration two-dimensional and three-dimensional electromagnetic pulse when it interacts with a composite of a polymer and graphene nanoribbons containing metal nanoparticles (atoms adsorbed on the graphene surface). Based on the wave equation, taking into account the contributions of the nanoribbons and polymer to the current, an effective equation for the vector potential of the electric field of the pulse is obtained. It is found that the introduction of metal adatoms into the polymer matrix causes a change in the amplitude of the wave propagating in such a system. The parameters of the electromagnetic wave are analyzed depending on the pulse type (two-dimensional and three-dimensional), the type of metal particle, and the concentration of the polymer in the composite.

Keywords: polymer composite, graphene nanoribbons, metal nanoparticles, electromagnetic pulses.
