Abstract
Recent theoretical and experimental results on light scattering from randomly rough surfaces have shown the importance of coherent effects in the presence of multiple scattering and symmetries. These coherent effects give rise to enhancements in the back-scattering, antispecular, or specular directions. Here, we present some recent experimental results of scattering from one-dimensional randomly rough surfaces with an even profile and from two-dimensional rough surfaces perpendicular to a mirror. These systems produce, respectively, enhanced specular and enhanced backscattering phenomena and are closely related. The similarities and differences between the two cases will be discussed, and, where possible, theoretical curves will be presented. The fabrication and characterization of the symmetric surfaces in photoresist will also be described.
