| Abstract: | In order to obtain the influence factors to the surface plasmon resonance (SPR) phenomenon, the effect of thickness of metal film, the refractive index of media and prism types on SPR have been systematically simulated by Winspall software based on thin film optics theory in this work. The optimum film thickness and the relationship between the refractive index and the resonance angle for Kretschman type SPR have been given, which provides a theoretical guidance for the design and optimization of SPR sensors. |
