Graphene has very good mobility and great tunability in the THz spectral region. These properties make graphene a perfect material for the study of surface plasmon resonance. In this thesis, we prepare a graphene-metal nano structure and investigate the surface plasmon resonance of graphene using Terahertz Time-domain spectroscopy measurement. First, we predict the surface plasmon resonance frequency from the theoretical model based on Maxwell equations then we compare the results of experiment with the theoretical prediction of the model.
