Book Description
The goal of this project was to improve our understanding of electromagnetic scattering from conducting rough surfaces when the roughness is small in comparison with the radiation wavelength. Research was conducted in two related areas for p-polarized scattering from conducting surfaces: the generation of surface waves, and the development of renormalized perturbation theory for scattering from perfectly conducting surfaces. To understand the excitation of surface waves better, a numerical method was developed for displaying the field near the surface; surface waves can then be shown explicitly. The method is based on integral equation solutions, and no fundamental approximations are required. The existence of surface waves for p-polarized scattering leads to difficulties in theoretical treatments of scattering from conductors. This work is specialized to the case of scattering from perfect conductors, for which the theoretical problems are most evident. A renormalized perturbation theory is implemented that is free from the deficiencies inherent in standard perturbation theory. The renormalized perturbation theory is extended beyond lowest order, and comparisons with exact integral equation results show that this approach yields predictions for the bistatic scattering cross section that are accurate over a broad range of surface parameters.

Book Description
The goal of this project was to complete a study of Bahar's full-wave approach to rough surface scattering that was begun under ONR support. The two proposed items of technical work have been fully completed. In the ONR-supported work, a study was begun for a simplified scattering problem: Scattering from a one-dimensional (1-D) surface with the Dirichlet (zero field) boundary condition using a Gaussian roughness spectrum. The full-wave method was implemented numerically and used in Monte Carlo calculations of the scattering cross section. Comparisons were then made with exact integral equation results, and with the Kirchholl and perturbation approximations. It was found that the full- wave prediction did not reduce to the lowest order perturbation prediction when the perturbation result was known to be accurate, as shown by exact calculations. This is contrary to conclusions reached by Bahar and is an important finding, showing that the full-wave approach is not as general as previously thought. The full-wave prediction did reduce to the Kirchhoff prediction when the Kirchhoff approximation is known to be accurate, as shown by exact calculations. In fact, the full-wave result was found to agree closely with the Kirchhoff result for all cases studied, whether or not the Kirchhoff result was accurate. (rrh).
