Abstract

This paper reports the design, development and characterization of a broadband, polarization insensitive metasurface absorber in planar, cylindrically bent and 90° dihedral surface geometry. Four metallic patches loaded with eight lumped resistors are used, which has been optimized numerically using CST MICROWAVE STUDIO, as a unit cell of developed metasurface absorber, to achieve 20 dB reflection reduction for 51.21% fractional bandwidth (13.42-22.66 GHz) under normal incidence with 0.12 [Formula: see text] thickness (where [Formula: see text] corresponds to lower operating frequency). The numerical findings are also verified analytically using equivalent circuit analysis, which exhibits very good agreement. Polarization-insensitive characteristics are achieved using fourfold rotation symmetry of the designed structure. The fabricated prototype of the designed absorber is experimentally characterized, using free space measurement method and ABmm vector network analyzer (VNA) system, and fairly good agreement with numerical-analytical findings are reported. The major novelty of this study is the design and development of a broadband (13.42-22.66 GHz), polarization insensitive metasurface absorber that provides 20 dB reflection reduction numerically as well as experimentally in the whole band, which to the author's knowledge has not been observed till now. Also, keeping in mind the radar stealth applications, first time we have demonstrated both numerically and experimentally, different geometrical shapes of conformal metasurfaces that can be practically used in actual scenario.

摘要

本文报道了一种宽带、偏振不敏感的超表面吸收体的设计、开发与特性，该吸收体具有平面、圆柱弯曲和90°二面角表面几何形状。使用了四个加载有八个集总电阻的金属贴片，作为所开发超表面吸收体的一个单元，利用CST微波工作室进行了数值优化，以在垂直入射、厚度为0.12 [公式：见正文]（其中[公式：见正文]对应较低工作频率）的情况下，在51.21%的分数带宽（13.42 - 22.66 GHz）内实现20 dB的反射降低。数值结果还通过等效电路分析进行了解析验证，两者表现出非常好的一致性。利用所设计结构的四重旋转对称性实现了偏振不敏感特性。使用自由空间测量方法和ABmm矢量网络分析仪（VNA）系统对所设计吸收体的制作原型进行了实验表征，并报道了与数值分析结果相当好的一致性。本研究的主要新颖之处在于设计并开发了一种宽带（13.42 - 22.66 GHz）、偏振不敏感的超表面吸收体，该吸收体在整个频段内数值和实验上均能实现20 dB的反射降低，据作者所知，此前尚未观察到这种情况。此外，考虑到雷达隐身应用，我们首次在数值和实验上都展示了可实际应用于实际场景的不同几何形状的共形超表面。
