Research progress of stealth materials/structures based on spoof surface plasmon polaritons

摘要:

面对未来战争陆、海、空、天、网、电“多域融合”的作战模式,新一代武器装备将强调拥有更高的隐身能力以增强其突防能力和生存能力,对隐身材料与结构提出了迫切的应用需求,亟需探索隐身新机理、开发高性能隐身材料与结构。人工表面等离激元(spoof surface plasmon polaritons,SSPP)是电子振荡与电磁振荡强烈耦合产生的一种混合模式,具有波长短、色散强等特点,在隐身、电子对抗等领域具有极为重要的军事应用价值。近年来,SSPP理论与耦合结构设计方法等快速发展,推动了SSPP在隐身技术中的应用研究。着眼于SSPP最新研究进展,结合SSPP色散特性,着重介绍了SSPP在波形畸变、吸波结构、隐身天线罩和隐身天线中的应用,最后对SSPP在隐身技术中的应用及发展趋势进行了展望。

Abstract:

With the advent of “multi-domain integration” operation mode for future war, the new generation of weapons and equipment should be of higher stealth ability to enhance their penetration capability and survivability. It is urgent to carry out research on new stealth mechanism, high-performance stealth material and structure. Spoof surface plasmon polaritons (SSPP) is a hybrid mode generated by the strong coupling between electron and electromagnetic oscillations. It exhibits the characteristics of shorter wavelength and strong dispersion, and has important application values in the fields of stealth, electronic countermeasures and others. In recent years, the development of SSPP theory and structure design has greatly enhanced the controllability of amplitude, phase, polarization, propagation mode of electromagnetic waves. Based on the latest research progress of SSPP in the field of stealth technologies, combined with the dispersion characteristics of SSPP, this paper focused on the application of SSPP in waveform distortion, absorbing structure, stealth radome and stealth antenna. Finally, the application and development trend of SSPP in stealth technologies were prospected.
