Abstract

We present an experimental study of the reflectivity of 2D randomly rough well-characterized, isotopic metallic surfaces. We proceed by comparing the experimental data with theoretical approaches of three perturbation theories and the Kirchhoff approximation. The samples were fabricated in photoresist, and their metallized surface profiles constitute good approximations to Gaussian-correlated, Gaussian random processes. The correlation lengths of these surfaces range form approximately one fifth to two times the IR wavelength employed.
