Investigation of plasmonic transmission in UT shaped graphene arrays

摘要

In this work, we studied the multi-band plasmonic UT graphene antenna arrays. The proposed model shows three different resonance frequencies. We show nearfield distributions of corresponding resonance frequencies and investigate the effect of the geometrical parameters, chemical potential, relaxation time, thickness of the substrate and different refractive index of the material on the spectral position of the UT-shaped graphene antenna.
