Garcia High-efficiency, Wideband Beam-scanning GRIN Lenses For Millimeter Wave Communications 2022 .txt text/plain 395 15 48 We identify two primary research tasks: 1) designing flat lens systems with high aperture efficiency over a wide bandwidth and 2) designing flat lens systems with wide-angle beam-scanning. The goal of this thesis is to provide a framework for designing flat GRIN lens systems that simultaneously demonstrate high instantaneous bandwidth, high aperture efficiency, and high beam-scanning capability in a practical form-factor. cache/wm117m0509s.txt txt/wm117m0509s.txt
