Abstract

Surface electromagnetic waves, known also as surface plasmons (SP), can be achieved if a polarized and collimated light beam undergoes total internal reflection at a glass/metal- film/dielectric interface. The SP phenomenon is observed (recorded) under resonance conditions as a sharp minimum of reflected light intensity (reflectance dip) when the angle of incidence of the laser beam is varied. Possibilities of the applications of this phenomenon to reflectometry of NaCl-water solutions were examined and some experimental results are presented.
