Graphene-Based Multifunctional Three-Port Far-Infrared Components
Victor Dmitriev, Geraldo Melo, Wagner Castro
Two graphene-based T-shaped multifunctional components for THz and Far-Infrared regions are proposed and analyzed. The first component can serve as a divider, a switch and a dynami…

THz graphene W-shaped three-port circulator with dynamical control
Victor Dmitriev, Wagner Castro, Geraldo Melo +2
We propose a new graphene-based THz circulator. It consists of a circular graphene resonator and three graphene nanoribbon waveguides of W-geometry placed on a dilectric substrate.…

Tunable THz and infrared plasmonic filter and switches based on circular graphene resonator with 90° bending of output port
Victor Dmitriev, Geraldo Melo, Wagner Castro
Two types of novel graphene-based components, namely, filters and electro-optical switches in guided wave configuration are suggested and analysed. The filters differ from the know…
