论文摘要
可重新配置的智能表面（RISS）是无线通信研究的新兴领域。用于分析和优化RIS授权的无线网络的基本组件是开发简单但充分精确的模型，用于RIS分散的功率。通过利用衍射的一般标量理论和Huygens试剂原理，我们引入了由RIS散布的电场的简单公式，该公式被RIS散布，该电场被建模为可忽略的厚度的电磁材料。所提出的方法使我们能够确定有限大小可以或不能作为异常的镜子近似的条件。说明了数值结果以确认所提出的方法。
Reconfigurable intelligent surfaces (RISs) are an emerging field of research in wireless communications. A fundamental component for analyzing and optimizing RIS-empowered wireless networks is the development of simple but sufficiently accurate models for the power scattered by an RIS. By leveraging the general scalar theory of diffraction and the Huygens-Fresnel principle, we introduce simple formulas for the electric field scattered by an RIS that is modeled as a sheet of electromagnetic material of negligible thickness. The proposed approach allows us to identify the conditions under which an RIS of finite size can or cannot be approximated as an anomalous mirror. Numerical results are illustrated to confirm the proposed approach.
