ABSTRACT
A broadband and broad-angle low-scattering metasurface is designed, fabricated, and characterized. Based on the optimization algorithm and far-field scattering pattern analysis, we propose a rapid and efficient method to design metasurfaces, which avoids the large amount of time-consuming electromagnetic simulations. Full-wave simulation and measurement results show that the proposed metasurface is insensitive to the polarization of incident waves, and presents good scattering-reduction properties for oblique incident waves.

Mentions: In order to verify the theoretical analysis above, a larger metasurface containing 16 by 16 units, optimized by the algorithm, has been fabricated and tested, as depicted in Fig. 6. The transmitting and receiving horn antennas have been connected to a vector network analyzer (Agilent N5230C) to measure the RCS of the metasurface.
