Electrically controllable active plasmonic directional coupler of terahertz signal based on a periodical dual grating gate graphene structure
Abstract We propose a concept of an electrically controllable plasmonic directional coupler of terahertz signal based on a periodical structure with an active (with inversion of the population of free charge carriers) graphene with a dual grating gate and numerically calculate its characteristics. P...
