Graphene based toroidal carbon nanostructures possess unique electronic properties induced by quantum confinement and cyclic boundary conditions imposed to the wave-functions along the circumference. We used a tight-binding approach to demonstrate that nanoribbon and nanotube based ring structures have energy-dependent selection rules for electron transmission, especially when they are connected to a large number of terminals.
