Multi-Facet Representation of Arbitrary Surface Geometries

This paper discusses the extension of array redundancy minimization techniques to arbitrary contiguous surfaces. By constructing a surface from an assemblage of facets and assigning each facet a location and orientation in global space, storage, compute time, and matrix fill time can be reduced. Included are general geometric formulations necessary to construct an arbitrary surface from preexisting facets, and discussions with regard to mesh integrity and storage reduction. The application of this technique to open surface PEC structures using moment method is illustrated
