Dielectric Carpet Cloaking Device Based on Feflection Phase Metasurface

Due to the extremely superior ability of ultrathin metasurfaces to reconstruct the wavefront, the study of the invisibility cloak is possible. However, the currently designed stealth cloak still has narrow bandwidth and application angle limitations, affecting the performance of the stealth cloak. In this paper, a highly variable transmission phase unit structure is proposed, and a dielectric metasurface carpet stealth cloak is constructed to achieve broadband and wide-angle characteristics. The proposed metasurface can effectively suppress scattering and reconstruct the wavefront. The carpet stealth cloak can realize the reflected wavefront control characteristics in the microwave range of 5 to 8 GHz, and can achieve stealth characteristics at the angle of incidence of 80°.
