摘　　要：智能超表面基于其对空间电磁波在幅、相和极化等参数上的调控,以可编程方式主动调控和定制化无线传播信道,已在多个领域初步展现了一定的潜力。然而,现阶段研究尚缺乏更全面的基于实际网络干扰假设的大规模系统级性能研究。对RIS系统级性能研究仿真方法论进行了探讨,分析了RIS系统性能研究中需要关注的关键维度和主要因素,并基于此对RIS系统级性能空间进行了研究。Reconfigurable intelligent surfaces(RIS)have demonstrated potential in various domains due to their ability to programmatically manipulate electromagnetic waves in terms of amplitude,phase,and polarization,thereby actively customizing wireless propagation channels.However,current research lacks comprehensive system-level performance studies based on realistic network interference assumptions.This article investigates the simulation methodologies for RIS system-level performance analysis,highlighting the critical dimensions and factors that need attention.Based on these insights,we further explore the performance landscape of RIS at the system level.
