© 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.We conduct a theoretical study and numerical simulations of terahertz radiation generation in the medium based on armchair-edge nanoribbons and zigzag nanotubes with metallic conductivity. The multicascade mechanism of radiation generation is considered in the task of terahertz radiation generation. The level of the injection current in nanoparticle arrays has been estimated. The task expands to the similar medium where radiation current is generated with the use of infrared radiation stimulated absorption, for example, radiation of a CO2 laser. For the effective dielectric function three basic models are employed: effective media approximation (Bruggeman’s theory) [nanotube bundles], Maxwell-Gatnett theory [ordered array], and Maxwell-Garnett theory with the Clausius–Mossotti geometric correction [ordered array of nanotubes].
