Broadband radar cross section reduction by in-plane integration of scattering metasurfaces and magnetic absorbing materials

An in-plane hybrid design is proposed to achieve broadband radar cross section (RCS) reduction based on the integration of a diffusion scattering electromagnetic band-gap (EBG) metasurface and a magnetic absorbing material (MAM) at a thin thickness (d). A scattering field calculation formula is deri...
