This document, the Final Performance Report for AFOSR Grant No. FA9550-12-1-0105, describes the research efforts of a group of six researchers in the fields of electromagnetics, radar and antenna technology. Research was conducted during this reporting period in the following technical areas 1 compressive sensing as applied to the processing of signals from sparse receive arrays 2 performance of the sparse fast Fourier transform for processing of coprime thinned phased arrays 3 a general anisotropic representation for spatially and temporally dispersive media that separates electric and magnetic polarization effects 4 plane-wave expansions with directional spectra 5 Gaussian-beam scattering-matrix theory 6 array realization of complex-source beams 7 metamaterial theory, including the fundamental homogenization theory of metamaterials and scattering from multilayered spheres 8 quantization lobe suppression for arrays of subarrays 9 asymmetric phased array elements and 10 current modes for efficient numerical phased array design.
