Abstract
In this letter, we investigate fully reconfigurable terahertz (THz) devices enabled by a T-shaped graphene two-parallel-sheet (GTPS). The proposed T-shaped GTPS is constructed by two series-connected GTPS sections and one shunt-connected open-ended GTPS section. By applying electrical gating to the T-shaped GTPS, both electrical length and characteristic impedance of the terahertz waveguide (i.e. T-shaped GTPS) can be fully tuned. To demonstrate the tuning feature of the T-shaped GTPS, a variety of tunable THz devices are designed based on it, including reconfigurable tunable THz transmission lines and a tunable THz coupler. The simulation results verify the large tuning range and multifunction of proposed devices.
