Angular correlation functions of light scattered from weakly rough metal surfaces

Abstract: The angular correlation functions of light diffusely scattered from weakly rough metal surfaces are studied. In experimental work, surfaces are well characterized, have highly one-dimensional roughness, and are studied in the case of p polarization. If there is significant plasmon polariton excitation, one type of intensity correlation function indicates that the diffuse intensity decorrelates rapidly as the angle of incidence is varied. It exhibits peaks that arise from an autocorrelation of identical intensi… Show more

“…The C 1 and C 10 correlations have been measured very recently in the scattering of p-polarized light from a one-dimensional, randomly rough, gold surface [25]. The roughness of the surface was characterized either by a Gaussian power spectrum of the form gjkj p p a exp Àa 2 k 2 a4, where a is the transverse correlation length, or by a West-O'Donnell power spectrum [26] given by gjkj pQjkj À k min Qk max À jkja k max À k min , where Qz is the Heaviside unit step function.…”

“…Diffuse reflectors are used in numerous applications such as the back‐lit units of liquid crystal display panels (LCD) to enable uniform distribution of light, light emitting diodes (LED) to enhance light extraction efficiency, solar cell devices to increase light trapping, and in coatings to reduce gloss. Surfaces with controlled roughness at the air/film interface can control diffuse reflection by omnidirectional scattering of light . This concept has been realized via fabrication of diffuse reflectors through vacuum deposition of metals, as well as via 3D lithography techniques .…”

“…A uniform surface with a controlled surface roughness reflects incident light in a diffusive manner and reduces specular reflection by randomly scattering light in all directions. [9][10][11][12] Controlling the ratio of specular and diffuse reflection is the most important aspect in the design of a diffuse reflector. Specific applications may require different ratios of specular and diffuse reflectance.…”
