Figure 13: The simulated and measured backward scattering coefficients versus frequency.

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

Figure 13

(a) Under normal x-polarized incident waves. (b) Under normal y-polarized incident waves. For the measured results in (a,b), the RCS of the metasurface and its metallic ground plane are separately measured first. Then, subtraction is made between their values.
