Generation of microwave and terahertz radiation in a medium of nanoparticles
We investigate the mechanism of radiation generation, whose source are modulated with the variable ( x - υ t ) surface currents in elongated nanoparticles forming a 3D structure. Carbon nanotubes and graphene nanoribbons are considered as elongated nanoparticles. The volume fraction f < < 1 of...

of nanoparticles is considered small (the distance between the centers of nanoparticles is several times greater than their length), thus allowing one to neglect the interaction of two identical nanotubes due to the tunneling effect. Since the velocity of modulated surface currents
