Research in Antenna Technology, Radar Technology and Electromagnetic Scattering Phenomena
Abstract
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.
