论文摘要
可重新配置的智能表面（RISS）是用于无线网络应用的新兴技术。我们介绍了一个物理和电磁（EM）符合电磁的通信模型，用于分析和优化RIS辅助无线系统。所提出的模型具有四个主要值得注意的属性：（i）它是端到端的，即，它是根据等效通道配制的，该通道在供电到发射机端口的电压与在接收器端口所测量的电压之间产生一对一的映射； （ii）它是符合EM符合的，即它解释了EM领域的产生和传播； （iii）它是相互耦合的，即，它解释了RIS的子波长单位细胞之间的相互耦合； （iv）它是单位电池所知，即，它解释了RIS单位单元单元的振幅和相位响应之间的相互作用。
Reconfigurable intelligent surfaces (RISs) are an emerging technology for application to wireless networks. We introduce a physics and electromagnetic (EM) compliant communication model for analyzing and optimizing RIS-assisted wireless systems. The proposed model has four main notable attributes: (i) it is end-to-end, i.e., it is formulated in terms of an equivalent channel that yields a one-to-one mapping between the voltages fed into the ports of a transmitter and the voltages measured at the ports of a receiver; (ii) it is EM-compliant, i.e., it accounts for the generation and propagation of the EM fields; (iii) it is mutual coupling aware, i.e., it accounts for the mutual coupling among the sub-wavelength unit cells of the RIS; and (iv) it is unit cell aware, i.e., it accounts for the intertwinement between the amplitude and phase response of the unit cells of the RIS.
