【摘要】 本文基于P B相位和卷积定理设计了钥匙形贴片和衬底的单元结构,根据梯度相位和波束偏转对编码序列进行排布,该太赫兹编码超表面可将入射波束转换成具有任意偏转角度的多波束,同时利用随机编码序列可实现良好的RCS缩减功能。因此,所提出的超表面在太赫兹调制和波束扫描器件以及室内通信方面具有潜在的应用前景。更多还原

【Abstract】 In this paper,the unit structure of key-shaped patch and substrate is designed based on PB phase and convolution theorem,and the distribution of the coding sequence is arranged according to the gradient phase and beam deflection,and this terahertz coding metasurface has the ability to convert the incident beam into a multibeam with arbitrary deflection angle,while good RCS reduction can be achieved using random coding sequence.Therefore,the proposed metasurface has great potential applications in terahertz modulation and beam scanning devices as well as indoor communication.更多还原
