This paper summarizes and synthetically evaluates a method proposed for metasurface design. The method takes as input a set of desired far-field (FF) performance specifications and produces an effective susceptibility distribution that, when illuminated with a known incident field, produces a FF radiation pattern exhibiting the desired specifications. To this end, electromagnetic inversion (inverse source) is used to solve for the desired tangential fields on the output side of the metasurface. A finite-difference frequency-domain solver, recently developed for simulation of metasurfaces, is used to synthetically evaluate the proposed method using a two-dimensional (2D) example. It should be noted that microscopic metasurface design (i.e., the design of the physical metasurface implementation) is beyond the scope of this paper.
