论文摘要
可重新配置的智能表面（RIS）可以帮助Terahertz无线通信恢复易碎的视线链接并促进光束转向。需要任意反射光束模式以满足不同应用中的不同要求。本文建立了RIS梁图案设计与二维有限脉冲响应滤波器设计之间的关系，并提出了一种快速的非题算法来解决该问题。模拟表明该方法的表现优于基线方法。因此，它代表了在RIS辅助Terahertz无线通信中快速和任意束图案设计的有前途的解决方案。
Reconfigurable intelligent surface (RIS) can assist terahertz wireless communication to restore the fragile line-of-sight links and facilitate beam steering. Arbitrary reflection beam patterns are desired to meet diverse requirements in different applications. This paper establishes relationship between RIS beam pattern design with two-dimensional finite impulse response filter design and proposes a fast non-iterative algorithm to solve the problem. Simulations show that the proposed method outperforms baseline method. Hence, it represents a promising solution for fast and arbitrary beam pattern design in RIS-assisted terahertz wireless communication.
