Cosite analysis of large, complex structures using novel facet-based multiscale and multiphysics techniques

A multiscale and multiphysics approach for performing cosite analysis of complex structures is described in this paper. We focus on recent advances in Uniform Theory of Diffraction (UTD) codes using facet-based techniques for antenna analysis that are hybridized with finite difference and partial element equivalent circuit methods, which have greatly improved the computational efficiency for cosite analysis. Such tools can also utilize other techniques to partition the problem for accurate results specific to different regimes moving from the exterior coupling problem to the adverse effects imposed on enclosed cavities and devices.
