  • D. E. Fernandes, M. Rodrigues, G. Falcão, M. G. Silveirinha, Prémio ANACOM-URSI 2015, The ANACOM-URSI Portugal Prize was assigned to “Diffractionless Propagation of Electron Waves in Graphene Superlattices”. In this work we used a homemade Finite Difference in the Time Domain (FDTD) algorithm to characterize the propagation of electron waves in graphene. The algorithm was applied to study the dynamics of electrons in graphene superlattices, using both microscopic and effective medium approaches. In particular, it is shown that the time evolution of an electronic state and the propagation of stationary electronic states may be accurately predicted with the effective medium formalism, provided the initial state is less localized than the characteristic spatial period of the superlattice. Our results confirmed that electrons propagating in graphene superlattices with extreme anisotropy experience virtually no diffraction, 01-12-2015
