Excerpt from Multiple Scattering of Waves by Planar Random Distributions of Parallel Cylinders and Bosses We derive closed-form representations which are valid at least when the minimum separation of cylinders is large com pared to radius and wavelength; these apparently suffice to take into account the largest effects of multiple scattering. We show that these representations hold either when there is a high degree of order in the distribution of neighbors, or for all distributions near grazing incidence. Other representations are also discussed. The most interesting result we obtain concerns the be havior near grazing incidence. Whereas the single-scattered wave may become infinite as grazing incidence is approached, the multiple scattered wave approaches the negative of the incident wave. Thus the results reduce to those for a dielectric plane near grazing incidence, the incident wave being perfectly reflected with the appropriate sign change.
