Abstract
Synchronous scattering and diffraction were demonstrated using reflectance from gold nanotextured surfaces at oblique (θiâ¯=â¯15° and 60°) incidence of wavelength λâ¯=â¯405â¯nm. Two samples of unique auto-correlation functions were cost-effectively fabricated. Multiple structure factors of their profiles were confirmed with Fourier expansions. Bi-directional reflectance function (BRDF) from these samples provided experimental proofs. On the other hand, standard deviation of height and unique auto-correlation function of each sample were used to generate surfaces numerically. Comparing their BRDF with those of totally random rough surfaces further suggested that structure factors in profile could reduce specular reflection more than totally random roughness.
