Design Of Broadband And Broad-Angle Low-Scattering Conformal Metasurface With Genetic Algorithm

In this paper, a design of conformal metasurface on to the cylinders is proposed. A 2 bit meta-atom is designed to cover the full 2 pi phase range, then an extended far field formula from the planar metasurface is employed together with genetic algorithm to achieve the pre-determined broadband and broad-angle scattering reduction. Numerical full-wave simulations demonstrate our design.
