Abstract : This report summarizes 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 results 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 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.
