Abstract : In the first Annual Technical Report (1 Mar 81 - 28 Feb 82) the principal elements of the full wave approach and its relationship to earlier solutions of scattering problems were summarized. For the convenience of the reader of this report, all the principal analytical results leading to full wave expressions for the normalized cross sections are presented in Section (1.1). Thus, starting with Maxwell's equations for the transverse components of the electromagnetic fields, the boundary conditions, the expressions for the complete field expansions and the associated orthogonal relations, the generalized telegraphists equations are derived. It is shown how these coupled equations are solved using a second order iterative approach and the judicious use of a local coordinate system that conforms with features of the rough surface. Explicit expressions for the scattered radiation fields and the like and cross polarized scattering cross sections are also presented. Thus the reader finds in this section a convenient review of all the background material that leads up to the general full wave expressions for the scattering cross sections.
