title = "Design and Optimization of 3D Meta-Volumes for Complementary Phases Enabling Wide Field of View RCS Reduction",
abstract = "Conventionally, the design of coding metasurface unit cells focuses on the performance at normal incidence. The traditional design process has been confined to working within the paradigm of two-dimensional planar or multilayer structures which inherently possess a limited field of view (FoV). Here, in a fundamental departure from this paradigm, a pair of three-dimensional unit cells are simultaneously optimized using a multi-objective genetic algorithm in order to firsthand design the unit cells for maximum performance at oblique incidence angles. These unit cells were then configured into a diffuse array for the purpose of RCS reduction. The surface reduces the bistatic, specular RCS (radar cross section) by 90% (10 dB) over a worst-case 63% bandwidth for oblique incidence of 70 degrees at Hx polarization and by 80% (7 dB) over a worst-case 70% bandwidth for oblique incidence of 45 degrees at Ex polarization.",
