A random walk through surface scattering phenomena: Theory and   phenomenology
  No surface is perfectly planar at all scales. The notion of flatness of a surface therefore depends on the size of the probe used to observe it. As a consequence rough interfaces are abundant in nature. Here the old, but still active field of rough surface scattering of electromagnetic waves is addressed. This topic has implications and practical applications in fields as diverse as observational astronomy and the electronics industry. This article reviews the theoretical and computational foundation and methods used in the study of rough surface scattering. Furthermore, it presents and explains the physical origin of a series of multiple scattering surface phenomena. In particular what is discussed are: the enhanced backscattering and satellite peak phenomena, coherent effects in angular intensity correlation functions and second harmonic generated light (a non-linear effect).
