Fig. 4

a Picture of the fabricated rhombic cloaking shell, which consists of the metasurface shown in Fig. 3 and a layer of ZIM composed of photonic crystals. The central part is a metallic rhombus as the hidden region with a λ/4 distance (10.2 GHz) of separation from the photonic crystal. b The electric field distribution for the case with the cloaking shell. The part inside the region marked by the green rectangle is experimentally obtained via a microwave field mapper. The other part is obtained by the full-wave simulation. c The electric field distribution for the case without the cloaking shell. The parts inside and outside the region marked by the green rectangle are obtained experimentally and numerically, respectively. The sources in (b, c) are both TE-polarized plane waves incident from the left. d Simulated power radiation patterns for a rhombic PEC scatterer with and without cloaks
