Abstract
In this thesis, we introduce the history of Surface plasmon resonance, and its development in recent years. Focusing on theoretical derivation and electromagnetic wave field analysis of the surface plasmon based sensor to obtain the principle for figuring out the effect of each parameters. Including thickness, refractive index, and corresponding incident angle of each layer. Furthermore, analysis about the TM polarized electromagnetic wave distribution between dielectric material and metal by using waveguide theory and couple mode theory. Based on above approaching to analyze the structure adding dielectric nano-layer with high refractive index on conventional Krestchmann’s geometry. We obtain much better sensitivity results than convention one and the principle might be applied in other application. Here the simulation software we use the software including RSoft, COMSOL and MathCAD to repeat the research done by former then compare with the design of this paper. Finally, we conclude the optimal design principle that most sensitive in change of refractive index respect to incident angle under different thickness layers and materials.
