Regular Normal Transmittance of Roughened Dielectric Interfaces: Comparison of Theory and Data
Abstract
The theory for the regular normal transmittance of a rough dielectric interface is compared with experimental results. Relative regular transmission data from a very novel experiment involving variation of interface refractive index ratio and root-mean-square (rms) roughness at a single wavelength are found to be in excellent agreement with the theoretical transmittance relation for a rough dielectric interface having a Gaussian distribution of surface heights. Also, absolute spectral transmission measurements for rock-salt (NaCl) windows roughened on both faces are found to be in good agreement with the regular transmittance theory at wavelengths where absorption and surface scattering are negligible.
