摘要

本文综述了近年来用于减小RCS的超材料和超表面的研究进展，包括基本理论、工作原理、设计公式和实验验证。由超表面介导的超薄斗篷可以在对原有电磁场分布影响很小的情况下覆盖物体。RCS减少可以通过使用编码元表面重新配置散射模式来实现。基于超材料的场增强特性，可以设计出新型的雷达吸波材料。超材料与传统的雷达吸波材料结合使用时，可以扩大吸波带宽、增大吸波角度范围或减轻吸波重量。总结了未来发展趋势和面临的主要挑战。

Recent developments of metamaterials/metasurfaces for RCS reduction

In this paper, recent developments of metamaterials and metasurfaces for RCS reduction are reviewed, including basic theory, working principle, design formula, and experimental verification. Super-thin cloaks mediated by metasurfaces can cloak objects with minor impacts on the original electromagnetic field distribution. RCS reduction can be achieved by reconfiguring scattering patterns using coding metasurfaces. Novel radar absorbing materials can be devised based on field enhancements of metamaterials. When combined with conventional radar absorbing materials, metamaterials can expand the bandwidth, enlarge the angular range, or reduce the weight. Future tendency and major challenges are also summarized.
