Abstract

The iterative upgrading of the means of warfare has promoted the development of detection technology, and military activities are increasingly demanding target stealth. In this paper, a multifunctional metamaterial absorber is recommended, which simultaneously realizes the integrated stealth functions of ultra-wideband radar wave absorption, low infrared emission, and optically transparent. The structure is composed of an infrared shield (IRSL), a radar-absorbing layer (RAL), and a reflective layer (RL). Simulation results indicate that the absorption bandwidth in the radar band (1.81-20.4 GHz) is more than 90%, and the infrared emissivity is as low as 0.271 in the IR band (3-14 μm). Moreover, it has the features of flexibility, angle stability (0-45°), polarization insensitivity (0-90°), and so on. Furthermore, the electric field current distribution and equivalent circuit model of the structure are analyzed, and a 180 mm*180 mm sample is built and tested; the results show that the simulated and actual measurements are in agreement, and it is expected that such absorbers will be used in areas such as aircraft.

用于雷达红外兼容隐形的透明宽带柔性超材料吸收器

战争手段的迭代升级促进了探测技术的发展，军事活动对目标隐身的要求越来越高。本文推荐了一种多功能超材料吸收器，它同时实现了超宽带雷达波吸收、低红外发射和光学透明等综合隐身功能。该结构由红外屏蔽层（IRSL）、雷达吸收层（RAL）和反射层（RL）组成。仿真结果表明，该结构在雷达波段（1.81-20.4 GHz）的吸收带宽超过 90%，在红外波段（3-14 μm）的红外发射率低至 0.271。此外，它还具有灵活性、角度稳定性（0-45°）、极化不敏感性（0-90°）等特点。此外，还分析了该结构的电场电流分布和等效电路模型，并制作和测试了一个 180 mm*180 mm 的样品；结果表明，模拟和实际测量结果一致，预计这种吸收器将用于飞机等领域。
