Fig. 1From: Coding Anisotropic Metasurface with Integrated Broadband Tunable Radiation and Low-Scattering PerformanceCoding EMMS and its constituent anisotropic element. a Coding EMMS consists of 4 × 4 pieces of anisotropic elements. The numbers of “0” and “1” elements are the same. Schematic geometry of the anisotropic “1” element (b) and “0” element (c) (a = 9 mm, l = 6 mm, m = 1 mm, h1 = 3 mm, h2 = 0.5 mm). d Flowchart of the SAA for finding the optimal coding matrixBack to article page
