摘要:
Parabolic phase is commonly utilized for concave or convex metalens. Here, we report for the first time using such approach for determinant diffusion of scattering waves in wide incident angles by arranging parabolic-phased subarrays in arbitrary coding sequences. To engineer multi-spectrum polarization-dependent bifunctional scatterings, multi-mode anisotropic meta-atoms are utilized without polarization cross-talking. For verification, two proof-to-concept coding metasurfaces are designed, fabricated and measured at microwave regime. Numerical and experimental results show that the -10 dB ba...
