论文摘要
可重新配置的智能表面（RISS）吸引了学术界和行业圈子的注意，因为它们能够控制渠道环境的电磁特性。但是，已经发现，RI的引入可能带来新的，更严重的网络共存问题。如果无法有效解决这些新的网络共存问题，它甚至可能进一步恶化网络性能。在本文中，提出并详细讨论了RIS网络共存模型，并深入分析了这些问题。进一步探索了两种新型的RIS设计机制，包括一种具有带外滤波器的新型多层RIS结构和RIS阻塞机制。最后，给出了数值结果和讨论。
Reconfigurable intelligent surfaces (RISs) have attracted the attention of academia and industry circles because of their ability to control the electromagnetic characteristics of channel environments. However, it has been found that the introduction of an RIS may bring new and more serious network coexistence problems. It may even further deteriorate the network performance if these new network coexistence problems cannot be effectively solved. In this paper, an RIS network coexistence model is proposed and discussed in detail, and these problems are deeply analysed. Two novel RIS design mechanisms, including a novel multilayer RIS structure with an out-of-band filter and an RIS blocking mechanism, are further explored. Finally, numerical results and a discussion are given.
