Miniaturized Periodicity Broadband Absorber With Via-Based Hybrid Metal-Graphene Structure for Large-Angle RCS Reduction
IEEE Transactions on Antennas and Propagation（2022）
摘要
In this article, we present a via-based hybrid metal–graphene metamaterial absorber with miniaturized periodicity, broad absorption band, and large-angle radar cross Section (RCS) reduction. The unit cell of the absorber is composed of a cross-shaped graphene film, four metal arrow-shaped patterns, and four cylindrical vias. By extending the length of vias and folding the shape of the pattern on t...
