Abstract: Abstract We theoretically investigate a dynamically tunable unidirectional reflectionlessness phenomenon by applying external voltage in a graphene plasmonic waveguide system based on far-field coupling among three resonators. The system consists of three wing-shaped resonators, which… read more here.
