摘要

自20世纪90年代首次用于生物系统的实时分析以来,表面等离子体共振(SPR)以其实时、无标记和无创的特性成为一种重要的光学生物传感技术。在本文中,我们回顾了介电-金属-介电平面波导中表面等离子体的电磁理论,并验证了一个新兴的计算包COMSOL的能力,它使用有限元方法(FEM)来分析等离子体现象。比较了解析法和数值法的计算结果,讨论了有限元求解的精度。

Surface plasmon in slab waveguide: A verification test-bed
Since its first use in a real-time analysis of a biological system in 1990s, surface plasmon resonance (SPR) has become an important optical biosensing technology for its real-time, label-free, and noninvasive nature. In this paper we review electromagnetic theory of surface plasmons in dielectric-metal-dielectric planar waveguides and verify capabilities of an emerging computational package, COMSOL, that uses finite element methods (FEM) for analysis of plasmonic phenomena. Results of analytical and numerical methods are compared and accuracy of FEM solver is discussed.
