Description: Author(s): Ariel Epstein and Oshri Rabinovich Metasurfaces offer versatile manipulation of light beams via low-loss, low-profile structures, but practical developments are impeded by heavy reliance on time-consuming full-wave simulations. In this study of m e t a g r a t i n g s , sparse periodic arrays of meta-atoms that can efficiently realize intricate field transformations, the authors present a detailed model based on capacitively loaded conducting wires. Perfect wide-angle beam splitters can be designed almost completely analytically, without the usual computational burden. The sensitivity of these metagratings to real-world imperfections is directly related to fundamental interference processes. [Phys. Rev. Applied 8, 054037] Published Mon Nov 20, 2017
