Abstract

Four articles have been accepted for publication in this special section on “Recent Advances on Absorbers/Rasobers and Their Applications on Antennas and EMC”. These articles cover four distinct topics: microwave absorbers, radar cross-section reduction through phase distribution across metasurfaces, the design of miniaturized rasobers, and the 3D microwave absorber with wide angular stability. In the first article, Ning et al. [A1] provide a design methodology based on characteristic mode analysis to design reconfigurable microwave metasurface absorbers. A broadband absorber design was reported with a step-bystep process, which was verified by a full-wave simulation and measurement of a fabricated prototype. A bandwidth of 105% from 3.6 to 11.6 GHz was accomplished with less than -10 dB reflection coefficient. In the second article, Al-Nuaimi et al. [A2] utilize a novel cusp phase distribution across metasurface to achieve radar cross-section reduction. Without the need for lengthy optimization, it was found that the cusp phase mask was able to achieve radar crosssection reduction of more than 10 dB over a bandwidth of 81.8%. A stable performance was accomplished under both the normal and oblique incidence up to 75°. In the third article, Zargar et al. [A3] propose a miniaturized rasorber design with dual transmission bands within a wide absorption band. A design flow of the proposed rasorber was presented to give an overview of the design process. The final design exhibits a wide absorption band from 3.7 to 14.6 GHz and two transmission bands were generated within that band at 10.7 GHz and 16 GHz with insertion losses of 1 and 0.7 dB, respectively. The simulated results were confirmed by a fabricated prototype and measurements. In the last article, Feng et al. [A4] propose universal equivalent transmission line (TL) model and design method for efficient absorption under large angles to synthesis the absorptive performance of an absorber. A prototype with 70° angular stability is designed as an example to validate the proposed methods, where the measurements agree well with the synthesized and simulated results. Specifically speaking, the measured average absorption ratios (ARs) under normal incidence, 45° incidence, and 70° incidence are 94.2%, 94.0%, and 92.3%, respectively.
吸收器/缓冲器的最新进展及其在天线和电磁兼容(EMC)方面的应用》特别章节客座编辑导言
本特别专栏 "吸收器/激光吸收器的最新进展及其在天线和电磁兼容性方面的应用 "已接受发表四篇文章。这些文章涉及四个不同的主题:微波吸收器、通过跨元表面的相位分布减小雷达截面、小型化吸收器的设计以及具有广角稳定性的三维微波吸收器。在第一篇文章中,Ning 等人[A1]提供了一种基于特征模态分析的设计方法,用于设计可重构的微波元面吸收器。他们采用分步法报告了一种宽带吸收器的设计,并通过全波仿真和制造原型的测量进行了验证。实现了 3.6 至 11.6 GHz 105% 的带宽,反射系数小于 -10 dB。在第二篇文章中,Al-Nuaimi 等人[A2]利用跨元表面的新颖尖顶相位分布来实现雷达截面减小。研究发现,不需要长时间的优化,尖顶相位掩模就能在 81.8% 的带宽范围内将雷达截面减小 10 dB 以上。在正常入射角和高达 75° 的斜入射角下,都能实现稳定的性能。在第三篇文章中,Zargar 等人[A3]提出了一种在宽吸收带内具有双传输带的小型化拉射器设计。文章介绍了所提拉索器的设计流程,以概述设计过程。最终设计显示了 3.7 至 14.6 千兆赫的宽吸收带,并在 10.7 千兆赫和 16 千兆赫带内产生了两个传输带,插入损耗分别为 1 和 0.7 分贝。模拟结果得到了制造原型和测量结果的证实。在最后一篇文章中,Feng 等人[A4]提出了通用等效传输线(TL)模型和大角度下高效吸收的设计方法,以综合吸收器的吸收性能。他们设计了一个具有 70° 角稳定性的原型作为例子来验证所提出的方法,测量结果与合成和模拟结果非常吻合。具体来说,在正常入射角、45° 入射角和 70° 入射角下测得的平均吸收比(AR)分别为 94.2%、94.0% 和 92.3%。
