Advanced Computational Methods for Study of Electromagnetic Compatibility

ABSTRACT: This effort focuses on development of efficient algorithms for the simulation of propagation and scattering of electromagnetic fields within and around structures that (i) Consist of complex combinations of penetrable materials as well as perfect and imperfect conductors, and, (ii) Possess complex geometrical characteristics, including open surfaces and metallic coatings, as well as geometric singularities: corners, edges and multi-scale featuresincluding geometries that contain simultaneously structures at length-scales at the level of electronics and complete aircraft. These are configurations of fundamental importance in diverse fields, with application to (a) Electromagnetic compatibility (EMC), (b) Electromagnetic interference on cavity-bound electronics (EMI), (c) Evaluation of electromagnetic response of dielectric/magnetic coated conductors, and (d) Evaluation of scattering by modern metallic/nonmetallic aircraft structuresamongst many others. The simulation of electromagnetic wave propagation in such complex structures gives rise to a host of significant computational challenges; these issues will be addressed through application of MathSys'innovative integral equation methodologies, with hardware implementations in both classical serial processors and large parallel infrastructures. In view of recent the Phase I work and other recent efforts, we submit the proposed consonant use of accurate and efficient mathematical algorithms and state-of-the-art numerical implementations will enable solution of previously intractable problems. BENEFIT: The PDE software needs of large high-tech companies, government labs and DoD (such as Lockheed Martin, Northrop Grumman, NASA, DoD agencies, etc.) are massive. MathSys Inc. is well positioned to cater to the needs of such entities, and has open ties at key levels of such organizations. We are certain that the successful completion of the proposed development effort will find manifold uses and it will generate significant business opportunities for our company.
