Metasurface from Hyperuniform Disordered Distribution

Abstract

Metasurface with different reflection phases have promised great possibilities in realizing diffusion-like backward scattering. In this paper, metasurface with unit cells based on hyperuniform disordered structure is presented. It is proven to be able to reduce Radar Cross Sections(RCS) in comparison with its counterpart design based on metasurfaces from periodic distribution. V-shape antenna is used as unit cell and ’1’ bit coding metasurfaces based on hyperuniform disordered structure and periodic structure are designed respectively. Numerical results show that metasurface with hyperuniform disordered structure generate more diffusion, which demonstrate larger bandwidth and higher RCS reduction compared with the corresponding metasurface based on periodic distribution.
