[Frequency-Diverse Reflection Metasurface Antenna Design for Computational Microwave Imaging] Aobo Li, Mengran Zhao, Dónal Patrick Lynch, Shitao Zhu, Muhammad Ali Babar Abbasi and Okan Yurduseven propose the design of a computational microwave imaging (CMI) oriented frequency-diverse reflection metasurface antenna (FDRMA). Designing a FDRMA for CMI requires a careful synthesis framework, from the topology of metamaterial elements to the statistical analyses of the metasurface and the evaluation of its CMI performance. Consequently, they begin with an investigation of different metamaterial element topologies with the aim to choose the optimal one to constitute a desired reflection metasurface. The FDRMA is then designed by randomly distributing the metamaterial elements with diverse structural parameters. The orthogonality of the reflected field patterns is investigated by means of a spatial-correlation evaluation and a singular value decomposition.
