Abstract :
Propagation features of the quasi-TEM mode supported by a graphene nano-ribbon placed on top of a grounded dielectric substrate are studied numerically with the Method of Moments in the spectral domain. A dyadic conductivity is adopted to model the graphene ribbon at microwave frequencies, taking into account the possible presence of static biasing fields and/or spatial-dispersion effects. Dispersion and attenuation properties are reported for typical values of the relevant physical parameters.
