摘要

本文利用斜入射光栅瓣理论和特征模态分析（CMA），提出了一种小型化的频率选择吸收器（FSR），它由具有广角稳定性的紧凑的频率选择表面（FSS）和具有宽吸收带的多模电阻负载吸收器组成。经过仿真优化和实验验证，实测结果表明，该FSR在3.3-6 GHz频段内实现了插损耗小于3 dB的高效传输，在8.7-16.5 GHz频段内实现了吸收率超过80%的宽带吸收。FSR在不同入射角和偏振下具有低姿态和稳定的响应，适用于紧凑型隐身平台设计。

Design of miniaturized frequency selective rasorber with high angular stability

In this paper, by utilizing the theory of oblique incident grating lobes and characteristic mode analysis (CMA), we proposed a miniaturized frequency selective rasorber (FSR), which is composed of a compact frequency selective surface (FSS) with wide-angle stability and a multimode resistor-loaded absorber with wide absorption band. After simulated optimization and experimental verification, the measured results indicate that the proposed FSR can achieve efficient transmission with an insertion loss of less than 3 dB within the 3.3–6 GHz band, and wideband absorption with an absorption rate of over 80 % within the 8.7–16.5 GHz band. The FSR exhibits a low profile and stable response at different incident angles and polarizations, making it suitable for compact stealth platform design.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
