Abstract
Bi-directional reflectance distribution function (BRDF) of one-dimensional random rough surface of aluminum is numerical analyzed using the finite-difference time-domain method. The effect of oxide film thickness on the BRDF is analyzed. The results show that the BRDF of one-dimensional random rough surface of aluminum is affected by the alumina film and the polarization state of incident waves. The effect of TE-wave on the BRDF is more significant than that of TM-wave. Specular spike is observed in the case of TE incident wave, and retro-reflection appears in the case of oblique TM incident wave. The peaks of BRDF of one-dimensional random rough surface of aluminum increase a little when the autocorrelation distance (τ) increases.
