Abstract
Dispersion, attenuation and characteristic impedance of the fundamental modes supported by a pair of identical graphene nanoribbons in free space are studied. An efficient full-wave approach is adopted, based on a method-of-moments discretization of the relevant electric-field integral equation in which the graphene is modeled through a simple local conductivity. A spatial-domain formulation is adopted as it allows for efficiently treating nanoribbons with wide transverse separations and having in mind future treatment of spatially nonuniform graphene conductivities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
