Optimization Methods for Direct and Inverse Problems in Electromagnetics.

Abstract

This report summarizes work carried out in the specific areas of inverse scattering and optimal-control problems in electromagnetics. Major accomplishments involve the modified gradient approach to inverse which was extended to the TE case, inhomogeneous background media, spatially limited frequency diverse data and the inclusion of a resolution enhancing total variation terms. In addition the complete family approach was further developed high frequency optimal current distributions were found for conformal antennas and additional results on low frequency asymptotics and a-posteriori error estimates in numerical solutions of direct problems were found.
