We propose a comprehensive field-based semianalytical method for designing\nfabrication-ready multifunctional periodic metasurfaces (MSs). Harnessing\nrecent work on multielement metagratings based on capacitively-loaded strips,\nwe have extended our previous meta-atom design formulation to generate\nrealistic substrate-supported printed-circuit-board layouts for anomalous\nrefraction MSs. Subsequently, we apply a greedy algorithm for iteratively\noptimizing individual scatterers across the entire macroperiod to achieve\nmultiple design goals for corresponding multiple incidence angles with a single\nMS structure. As verified with commercial solvers, the proposed semianalytical\nscheme, properly accounting for near-field coupling between the various\nscatterers, can reliably produce highly efficient multifunctional MSs on\ndemand, without requiring time-consuming full-wave optimization.\n
