In this paper, we propose the tuning of the optical nano antenna in the visible spectrum using graphene. A dipole structure for the nano antenna is considered with the resonating wavelength at the VIS-NIR spectrum range. Resonance is determined using the scattering characteristics of the dipole antenna. Placing monolayer and bilayers of graphene sheets on top of the optical nano antenna will result in a change in the resonating wavelength. The input impedance of the resultant structures is calculated. The FDTD simulation results for resonance characteristics were verified with the experiment results. Such architecture of graphene on top of the dipole nano antennas can be used for different biological and chemical gas sensors. |
