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.
