Abstract
Using a surface roughness model consisting of narrow columns of differing heights, the spectral transmittance and front and backside reflectance have been derived for a single layer on a smooth substrate. The effects of various amounts of surface roughness have been compared to various amounts of layer absorption. Surface roughness causes a more rapid loss of modulation with wavelength in transmission than absorption. It begins to act like incoherent light, which shows no wavelength fringing.
