摘要

在实现降低RCS方面，与天线集成的吸收频率选择反射结构(AFSR)是构建低RCS天线系统的有效方法。本文提出并研究了一种基于磁性材料的可重构AFSR，它由可重构频率选择表面(FSS)和频率相关磁性材料(FDMM)组成。总厚度为11.2 mm的可重构AFSR通过控制引脚二极管的ON和OFF状态，实现了5至8 GHz宽带吸收和- 10 dB反射率以及带内反射和带外吸收模式之间的切换。对所提出的结构进行了模拟和分析，得出了合理的一致结论。

Reconfigurable Absorptive Frequency-Selective Reflection Structure Based on Magnetic Material

When it comes to the realization of RCS reduction, absorptive frequency-selective reflection structure (AFSR) integrated with antenna is effective at building a low-RCS antenna system. In this article, a reconfigurable AFSR using magnetic material is proposed and investigated, which is comprised of a reconfigurable frequency selective surface (FSS) and a frequency-dependent magnetic material (FDMM). The total 11.2 mm thick reconfigurable AFSR realizes switches between broadband absorption from 5 to 8 GHz with −10 dB reflectivity and in-band reflection & out-of-band absorption modes by controlling the ON and OFF states of pin diodes. The proposed structure is simulated and analyzed, where reasonable agreements between these results are observed.
