Analysis of Surface Plasmons in the Optical Planar Waveguide with Spectral Detection

摘要

The paper deals with investigations concerning the plasmon resonance in an optical planar waveguide structure, applied in the construction of sensors with spectral detection. The surface plasmons in a multi-layer planar structure (with complex refractive indices) have been described, as well as the way of numerical solutions of physical equations describing the propagating electromagnetic field in such structures. The physical interpretation of obtained results has been presented, too.
