Abstract:   (508 Views)
In this paper, a plasmonic crystal switch is presented based on the graphene at the terahertz frequency. The amounts of transmission through the structure and reflection on the top of the device have been calculated numerically. The effects of changes in the radius of the circular aperture and the lattice constant of the crystalline structure were assessed on the transmission spectrum of the device. An increase in the chemical potential which is equivalent to an increase in the bias voltage leads to a frequency shift in the transmission spectrum in the structure. Hence this structure can be used as an ON/OFF switch in terahertz frequency. The extinction ratio for this switch is 8 dB and another advantage of this switch is that this structure can be easily fabricated.
