Wideband RCS Reduction Using Coding Diffusion Metasurface. [PDF]

Materials (Basel), 2019
This paper presents a radar cross-section (RCS) reduction technique by using the coding diffusion metasurface, which is optimised through a random optimization algorithm. The design consists of two unit cells, which are elements ‘1’ and ‘0’. The reflection phase between the two-unit cells has a 180° ± 37° phase difference.
