  • 人工局域表面等离激元结构具有许多特殊的光学性质, 对于新一代光学元件的设计具有重要的意义. 本文设计了一种在硅盘中周期性嵌入金属条的结构, 从而使得物体在任意方向的光散射均被抑制, 实现了全方向隐身的效果. 通过理论分析与数值模拟, 发现这种空心的人工局域表面等离激元结构在一定频率下会出现强散射抑制现象, 这是由结构的散射波与背景波之间干涉相消产生的效果, 且由于结构是一种周期性环状结构, 因此可以在散射抑制的频率点下实现全方向的隐身效果. 这为分析人工局域表面等离激元结构的物理隐身和光学响应提供了一条新的途径. 此外, 本文还分析了结构在不同参数条件下对散射谱移动规律的影响. 本文的结果适用于微波到太赫兹波区域, 可以应用于各种先进的光学器件, 如雷达、隐身涂层、传感器和探测器等.
    Surface plasmons include surface plasmon polaritons and localized surface plasmons, which are electromagnetic wave confined at the interface of the metal and dielectric. Spoof surface plasmonic structure has many special optical properties, which is of great significance for designing new-generation optical elements. In order to transfer the features of the surface plasmon polaritons and localized surface plasmons to microwave-terahertz region, Pendry et al. (Pendry J B, Martin-Moreno L, Garcia-Vidal F J 2004 Science 305 847) have proposed the spoof surface plasmon polaritons based on a metal structure with grooved stripes. In this paper, a hollow textured perfect electric conductor cylinder with periodic cut-through slits structure is designed to suppress the light scattering of the object in any direction and achieve the effect of omnidirectional cloaking while the transverse magnetic polarization wave propagates along the x direction. And the locations of the electrical and magnetic modes can be freely modulated by tailoring the structural geometric construction. In order to find the physical mechanism behind the abnormal phenomenon, through theoretical analysis and numerical simulation, we find that the strong scattering suppression of this spoof surface plasmonic polariton structure is caused by the interference between the background wave and Mie scattering of the structural unit, and it can be equivalent to a ring metamaterial due to the special structural design, in order to achieve the omnidirectional cloaking. It implies that we can hide objects in metal strips due to the fact that the metal in the microwave-to-terahertz region is equivalent to a perfect electrical conductor. This opens up a new way to analyzing the physical cloaking and optical response of spoof surface plasmonic polaritons structure. In addition, we also analyze the influence of the structure on the movement law of the scattering spectrum under different structural parameters. This enables us to have an in-depth understanding of the influence of structural parameters on the structural scattering spectrum. Our results can be applied to the microwave-to-terahertz region and a variety of advanced optic devices such as radars, cloaking coatings, sensors and detectors.
