Figure 1: Geometry of the basic meta-atom and its reflection properties.

From: Ultra-wideband, Wide Angle and Polarization-insensitive Specular Reflection Reduction by Metasurface based on Parameter-adjustable Meta-Atoms

Figure 1

(a) Geometry of square ring element. Dimensions are: a = 3, w = 0.3, h = 1.5748 in mm. (b) Reflection magnitude and (c) Reflection phase versus frequency with the change of side length L. (d) The available phase coverage in the frequency range from 5 to 55 GHz. The subtraction is made between two phase curves of the smallest size (L = 0.8 mm) and biggest size (L = 2.9 mm).
