Various optics-inspired electronic devices based on graphene have been proposed, owing to the linear dispersion relation of the charge carriers. In this contribution, the waveguide bend is examined by means of a higher-order time-domain method for the (2+1)D Dirac equation and it is demonstrated that, because of the peculiar properties of graphene, sharp waveguide bends with low losses are achievable even when Dirac point fluctuations are taken into consideration.
Because of their long mean free path and superior current-carrying capabilities, carbon nanotubes (CNTs) are considered as an alternative for Cu in future interconnects. To
The non-equilibrium Green’s function formalism is often employed to model photon-assisted tunneling processes in opto-electronic quantum well devices. For this purpose, self-consistent schemes based on
In this paper, the exact differential surface admittance (DSA) operator for scattering analysis of a homogeneous dielectric sphere is constructed. By utilizing two sets of
