Under this AFOSR GameChanger we carried out groundbreaking research by developing methods and materials to realize small and conformal structurally integrated antennas for unmanned airborne vehicles UAVs. We are proud to report several groundbreaking developments in all areas. Among them we a developed a conformal, load-bearing antenna technology by embroidering e-fibers on polymer composites, b Characterized performance of the e-fibers in terms of core and specific strength for load-bearing applications, c Developed a new principles DFT method for systematic search of ferromagnetic, low conductivity nanowires, d Developed a strategy for increasing permittivity and permeability proportionately using magnetic nanowires combined with conventional high contrast materials for antenna miniaturization, e demonstrated theoretical feasibility of laminate EM materials that alter wave propagation characteristics, critical to future miniaturization efforts, f Developed a multi-time scaling model and algorithm for coupling mechanical and EM solutions in real time, critical to multiphysics coupled EM-Structural analysis, g Extended our new domain decomposition algorithm to 3-D space and characterized more complexintricate details on large platforms such as e-fibers embroidered on UAV platforms. In addition to this report, our ground breaking work under this program has been published in over 120 journal papers and over 70 conference summaries.
