The surface databases provide data for surface analysis by Auger-electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS). In simple words, the refractive index describes how fast a light beam travels through media, and this. Theoretically even for Fresnel reflection in dielectric. Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion. For engineering calculations real part sometimes is less than 1.

Imagine part shows the extinction coefficient k - absorption in a material. It is a dimensionless number that depends on temperature and on the wavelength of the light beam. Metals refractive index is always complex number (and not only for metals).
