| description | Possibility of tuning the optical response of a Nano dipole antenna by using various plasmonic based materials is demonstrated. By incorporating various load geometry in Nano dipole antenna’s gap, different optical characteristics of Nano dipole antennas, e.g. extinction cross section (ECS), input impedance, scattering cross section (SCS), has been numerically investigated. It is shown that by properly design, based on desired goal, tunable and broadband absorption cross section can be achieved. In addition, a graphene based load is also incorporated, and multiple peaks for ESC at THz band was showed. |
