中文摘要：

提出了宽带雷达散射截面（radar cross section, RCS）减缩人工磁导体复合结构,通过将多个金属方片周期结构相复合,进一步拓展了其工作带宽.测试结果表明,反射率小于？10 dB的频段为7.7—13.1 GHz,相对带宽为51.9%.通过全波仿真研究了其在不同频率的散射特性,随着频率的增加,在对角象限平分面上的反射峰逐渐向法线方向靠拢,但其RCS较金属板的后向RCS仍减小？8 dB以上.该人工磁导体复合结构具有工作带宽大、设计简单和加工容易等优点,具有重要的应用前景.

英文摘要：

We propose a broadband artificial magnetic conductor （AMC） composite structure for reducing radar cross section （RCS）. By combining multiple periodic metal square patches together, we further broaden the working bandwidth of the AMC composite struc-ture. The tested results indicate that the reflection is below？10 dB in a frequency range of 7.7—13.1 GHz, and the relative bandwidth is 51.9%. We study the scattering characteristics of the AMC composite structure at different frequencies by full wave simulation. Reflection peaks in the opposite quadrant bisector of plane shift close to the normal direction with the increase of frequency, but the backscattering RCS of the AMC composite structure is still about？8 dB smaller than that of the metal plate. The AMC com-posite structure has the advantages of broad working bandwidth, simple design, easy processing, etc, and has important application foreground.
