Inverse and Control Problems in Electromagnetics

Abstract

This report summaries work carried out in a number of specific areas of investigation in inverse scattering and optimal control problems in electromagnetics. The progress is briefly described and detailed result's are included in an appendix. The major accomplishments include: the application of multi-criteria optimization techniques to problems in antenna design; the development of inverse scattering algorithms which use scattered field data in the frequency domain to reconstruct the shape, location and constitutive parameters of a scattering object; establishing the well-posedness of electromagnetic scattering problems with resistive or conductive boundary conditions; and derivation of new boundary integral equations for electromagnetic scattering from local distributions of a plane screen. In addition some new results on low frequency scattering have been found which establish the exact nature of the asymptotic expansion in two dimensions. Antenna design, Multicriteria optimization, Inverse scattering, Low frequency scattering, Integral equations.
