Suppression of Specular Reflections by Metasurface with Engineered Nonuniform Distribution of Reflection Phase

Figure 7

Simulated backscattering patterns under -polarized normal incidence at 4 GHz for (a) the nonuniform surface as instance and (b) the naked conducting surface. The far-field intensity involved in this figure is the synthesized quantity . Both patterns are normalized to the specular far-filed intensity of the conducting surface and the values below −50 dB have all been truncated.
