Computational Electromagnetics Application to Small Geometric Anomalies and Associated Ucertainty Evaluation
Abstract
The work performed under this effort has resulted in development of variety of important computational-electromagnetics tools enabling efficient application to problems involving small geometric anomalies and associated uncertainty evaluation, including: (1) Issues related to highly efficient implementations of integral EM approaches suitable for extension to high-performance parallel solvers; (2) Surface repair and representation of openings and surface variabilities and methodologies for surface repair of highly-damaged or highly-inaccurate geometry representations; (3) Consideration of issues related to uncertainty quantification for both continuous and discrete random variables, with special attention to the context of EMC/EMI, and development of adaptive stochastic collocation and reduced order modelling methods; and (4) Development of integral-equation solvers for electromagnetic scattering by wire antennas and open surfaces, with attention to solution singularities, pseudo-differential character of the integral operators, and associated spectral distributions and required numbers of GMRES iterations.
