The gold nano-antenna structure was arranged by nano manipulation of Atomic Force Microscope (AFM). The pattern of gold nano-antenna includes cross type, vertical type, chain type and three-pronged type. Moreover we measured transmission and absorption spectrum by Leica spectral photometer. The differences of transmission and absorption spectrum of gold nano-antenna structure was studied in thesis. And we can observe that the three-pronged structure has blue-shift in absorption spectrum while the gap becomes closer by nano manipulation. In additional, we can observe the inverse T-shape structure has red-shift in absorption spectrum by different polarization with 90o, 45o and 0o. And we assume that these results were due to the surface plasmon resonance (SPR).
