ABSTRACT
This chapter discusses the electrodynamic properties of a new graphene/carbon nanotube composite material. New nanomaterials based on graphene and carbon nanotubes (CNTs) are extremely promising in optical communication. The chapter presents the results of modeling of properties and exploring the prospects of the new hybrid CNT/graphene two-dimensional (2D) composite as an element base for new-generation optical modulators. The thickness of the film is determined by the tube diameter and the degree of strain. The tubes were slightly deformed, and the graphene became corrugated. To determine the reflection, transmission, and absorption parameters, Maxwell’s equations for electric and magnetic fields in vacuum with a 2D CNT/graphene composite as the interface were solved. The intensity of peaks for a CNT/graphene film is higher than for pure graphene and isolated nanotubes. The composite is capable of absorbing waves in the extended range in comparison to individual tubes and ideal graphene.
