Metasurfaces composed of subwavelength unit cells usually require a large number of unit cells which lead to complicated design and optimization. Aggressive discretization in metasurface designs can significantly reduce the number of unit cells within a period, resulting in large unit cell sizes. The enlarged unit cells will encounter negligible mutual couplings when combined together, hence making straightforward the process of metasurface design. These advantages combine to allow the design…
