摘要：

Reported is on the observation of surface plasmon resonances showing sharp maxima in the reflectivity of transverse magnetic visible radiation. Two systems of thin layers are examined, a bilayer of vanadium/gold, and a trilayer of iron/magnesiumfluoride/silver. Theoretical reflectivity data derived from Fresnel equations have been fitted to our experimental data in order to find the optical constants and layer thicknesses of the two systems. These parameters have then been used to model the optical field profiles, thus illustrating the nature of the surface plasmon resonances associated with the observed reflectivity maxima. Further, the potential of this type of surface plasmon resonance for sensing applications is investigated.
