The surface plasmon resonance (SPR) is one of the most attractive and precise enabling mechanism for sensors in biomedical applications. Conventional biological experiments are performed manually, time consuming intervention and expensive interconnection techniques. This paper simulates three dimensional behavior of magnetic and electric fields of light coupled into a SPR mode propagating along a thin gold layer surrounded by symmetric dielectric layers. This study successfully illustrates the three-dimensional simulation of surface plasmon wave using finite element method in COMSOL Multiphysics suit.
