In this work, a metasurface-based radome composite (MRC) with customized electromagnetic (EM) functions is proposed. By employing beam-scattering mechanism, high transmission at 2–4 GHz and significant radar cross-section (RCS) reduction 8–18 are achieved. The MRC prototype features sandwiched construction fabricated using quartz fiber-reinforced (QFRC) skins, polymethacrylimide (PMI) foam cores, silver-based frequency selective surface (FSS) screens. calculation, simulation, measured results demonstrated that the of planar specimen larger than −1 dB RCS less −10 GHz. also verified in HH VV polarizations, mono-static square pyramid (SP) specific directions from 8 to 12 significantly reduced. It believed our finding has great application potential stealth technology.
