Electromagnetic Analysis of Graphene Nanoparticles Operating in the TeraHertz Band

摘要

In this work electromagnetic properties of a new type of graphene nanoparticles are investigated. The particles consist of graphene circular and square rings, embedded in a dielectric environment. The electromagnetic behavior in terms of resonant frequency position, magnitude and amplitude width for the absorption cross-section and the near electric field distribution are evaluated. Moreover, the influence of the geometrical parameters is also evaluated. The electromagnetic analysis is derived through proper full-wave numerical simulations. Numerical results show that the nanoparticles can be successfully used for the development of future graphene-based antennas operating in the TeraHertz Band.
