Advanced Computational Methods for Study of Electromagnetic Compatibility
Abstract
We have developed a variety of electromagnetic scattering solvers whose combined use enables solution of a wide range of problems in the field of electromagnetic compatibility. In particular, we 1) Developed surface integral equations for homogeneous and isotropic dielectric bodies whose bounding surfaces can contain corners and edges, and that incorporate regularizations which give rise to favorable eigenvalue distributions and small numbers of GMRES iterations; 2) Implemented a fast high-order solver for dielectric-body integral equations introduced per point 1 above, for dielectric bodies containing edges and corners, allowing for use of overlapping and non-overlapping patches; 3) Developed new EM scattering solvers for open metallic surfaces for scatterers containing edges and corners; 4) Initiated a study to determine the domains of applicability of impedance boundary conditions through comparisons with full numerical solutions for thin volumetric conductors; and 5) Produced a new Green-function/Integral-Equation methodology for solution of problems involving two dimensional periodicity in three-dimensional space. This is the first approach ever developed that can successfully solve bi-periodic scattering problems in three-dimensional space at and around Wood anomaly frequencies. Finally, the qualities of all solvers developed were demonstrated via compelling applications to configurations relevant to the field of electromagnetic compatibility.
