A Simulation of Prism-based Surface Plasmon Resonance Liquid Sensing Device

The performance of a surface plasmon resonance (SPR) sensor including the excitation wavelength, gold film thickness and refractive indices of prism was studied theoretically. The narrowness and depth of the SPR curve were observed to improve the sensitivity of SPR sensor. The simulation results indicate that these parameters can be varied to produce a better performance of SPR sensor at an accuracy of more than 95%. This work is an important step to obtain the optimization of experimental parameters in order to design a high performance of SPR based sensing devices.
