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.
