RT Journal Article T1 Surface plasmon excitation in fiber-optics sensors: a novel theoretical approach. A1 Esteban Martínez, Óscar A1 Alonso Esteban, Rafael A1 Navarrete Fernández, María Cruz A1 González Cano, Agustín AB A theoretical method for the study of surface plasmon excitation in metallic layers, as used in fiber-optics sensors, is presented. It is based in the calculation of the propagated fields in the waveguide structure and allows us to compute the loss of optical power in the fiber (which is the measured parameter) from energy conservation considerations. The agreement with experimental data obtained with real sensors is good. The method is conceptually simple and can be adapted to different configurations of the sensors. PB IEEE - Inst.
