Surface Roughness Measurements Utilizing Long-Range Surface-Plasma Waves

Abstract

The contract performed an experiment to measure the dispersion of the long-range surface-plasmon polaritons as a function of the metal thickness along which they propagate, developed a theory for the profile of the light reflected from the prism-metal structure, and performed an experiment to observe this shape. Preliminary calculations (submitted in the interim report) indicate that our system is capable of measuring surface roughness of thin metal films down to several angstroms. Keywords: Thin films; Surface plasmon polaritons.
