Abstract
In this work, we introduce a plasmonic platform based on UT-shaped graphene antenna arrays. The proposed multi-resonant platform shows three different resonances, which can be independently tuned. The physical origin of these modes is shown with finite-difference time-domain (FDTD) nearfield distribution analyses, which are used to statically tune each resonance wavelength via the geometrical parameters, corresponding to different nearfield localization. We achieve statistical tuning of multiple resonances also by changing the number of graphene layers. Another static tuning of the optical response of the UT-shaped graphene antenna is achieved via the chemical potential and the relaxation time. Keywords
