“…For instance, in ocean remote sensing, it is used in the Ament model [5,6,16,17] to calculate the grazing incidence forward (i.e., in the specular direction) radar propagation over sea surfaces, in optics to determine optical constants of films [7,8] and other applications [9][10][11][12][13][14][15], or in indoor propagation, in ray-tracing based wave propagation models that take the wall roughness into account by introducing a power attenuation parameter [21][22][23][24][25].…”
