摘　　要：在基于ATR方法的SPR传感器设计和制作的工作中,为了得到更加优化的性能,对其原理进行了较为深入的分析。从表面激元波和全反射消逝波的数学模型入手,得到了共振角的数学关系及几个结论,并以金膜为例进行了计算机仿真。Do some indepth theoretical analysis in the work of designing and making surface plasmon resonance sensor(SPR)in order to obtain optimum performance.The discuss is emphasized on the principle of SPR sensor based on Attenuated Total Reflection(ATR)prism coupling method through the mathematical model of Surface Plasmon Wave(SPW)and attenuated wave in total reflection.Several conclusions such as mathematical relation between refractive index of analyzed layer and resonant angle and so on have been drawn,and simulated by computer in case of golden film.
