Geometry of rough surface scattering problem, in which an incident plane EM wave illuminates a three dimensional fractal rough surface patch of size (2[L.sub.x] x 2[L.sub.y]) at an angle of incidence equal to [[theta].sub.1].
NSiteMatch aims at identifying similarity between local surface patches; that is, it calculates a similarity score between a binding site (template) and a surface patch of the target protein.
