新型电磁波隐身研究进展

Progress of novel electromagnetics cloaking research

随着科技的发展,隐身逐步从一种简单、朴素的视觉欺骗手段,走向一种精准化、系统化的现代技术体系.通过设计合理的电磁参数,新型电磁波隐身技术能够灵活地调控电磁波的传播与散射,从而降低被隐身物体的可探测性.新型隐身器件的电磁参数可以通过人工设计微纳结构的方法来实现,也可以结合自然界中已存在的介质来制备.本文在详细介绍新型电磁波隐身研究进展的基础上,探讨了这一领域所面临的难点和挑战,并对未来的发展做了展望.

With the development of science and technology,the invisibility has gradually moved from a simple and plain visual deception trick to a precise and systematic modern technology system.By designing appropriate electromagnetic parameters,the novel electromagnetic wave cloaking technology is able to control the propagation and scattering of electromagnetic wave,thereby reducing the detectability of the cloaked object.The electromagnetic parameters of these novel cloaking devices can be realized by using the artificially designed nanostructures,or by combining the medium that already exists in nature.In this review,according to a detailed introduction of the research progress of novel electromagnetic wave cloaking,we discuss the difficulties and challenges in this field,and give an outlook on the future development.
