论文摘要
在本文中，我们介绍了一种称为Omni-Digital-Riss（DRISS）的可重构智能表面（RISS）的变体，该变体允许多个物理过程，并应用于光学无线通信系统。所提出的Omni-Dris既包含反射器和折射元件，又包含同时执行的元素。我们描述和解释Omni-Dris的概念，建议和分析Omni-Dris编码结构，讨论要使用的超材料，并提供设计示例。此外，我们证明了Omni-Dris系统的可实现速率取决于Omni-Dris元素的数量，每个相移的位和未使用元素的数量。此外，我们表明可实现的速率上限与Omni-Dris元素的数量有关，并通过讨论未来的研究方向来得出结论。
In this paper, we introduce a variant of reconfigurable intelligent surfaces (RISs) called omni-digital-RISs (DRISs), which allow multiple physical processes, with application to optical wireless communications systems. The proposed omni-DRIS contains both reflectors and refractive elements, as well as elements that perform both simultaneously. We describe and explain the concept of omni-DRIS, suggest and analyze an omni-DRIS coding structure, discuss metamaterials to be used, and provide a design example. Furthermore, we demonstrate that the achievable rate of an omni-DRIS system depends on the number of omni-DRIS elements, bits per phase shift, and the number of unused elements. In addition, we show that the achievable rate upper bound is related to the number of omni-DRIS elements, and conclude by discussing future research directions.
