Analysis of Electronic Waveguide Bends in Graphene Subject to Dirac Point Fluctuations

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.
