Abstract

The optical absorption in small cubic particles and thin films, composed of an ionic crystal or a free-electron metal, is calculated by using both a local dielectric constant and more-exact microscopic methods. It is found that a local theory gives a qualitatively correct description of the absorption in cubes but not in thin films. The electric field is calculated in thin metallic films, and the results are applied to the theory of surface-enhanced Raman scattering.
