BRUCE, N.C.. Randomly rough rectangular-groove surfaces with predetermined backscatter intensities. Rev. mex. fis. [online]. 2006, vol.52, n.3, pp.246-254. ISSN 0035-001X.
The backscattered intensity of the scattered light in rectangular-grooved surfaces is used as a design parameter for randomly rough surfaces. A modified Kirchhoff method and the integral equation method are used to calculate the scattered light distribution for these designed surfaces. The results of the two calculation methods are found to show good agreement, with the Kirchhoff method slightly overestimating the double scattered intensity, perhaps due to the limitations of the geometrical shadow functions used in this method. These results show that the backscattered intensity can be controlled in this type of surface.
