| الوصف: | In this paper, a hybrid checkerboard metasurface is proposed for controlling radar cross-sections (RCSs) using a small number of active devices. The proposed metasurface consists of passive and active artificial magnetic conductors. The passive metasurface contributes to reducing the RCS level owing to the dispersion characteristics of the checkerboard arrangement, while the active metasurface aids in controlling the RCS. The active RCS pattern of the proposed hybrid checkerboard metasurface in response to changes in phase distribution is also investigated. The results show that the RCS level at the boresight changed from −20.3 dBsm to 4.4 dBsm, and the main lobe of the RCS pattern steered up to 31°. The fabrication and measurement results of the proposed hybrid checkerboard metasurface are also described in this study. |
