MATLAB Simulation Package for Reconfigurable Intelligent Surface (RIS) Modeling Based on an Antenna Array-Like Approach

This dataset includes the MATLAB program "RIS_Simulator_CNIT.mat" and its associated functions, developed to simulate the behavior of Reconfigurable Intelligent Surfaces (RIS) using a macroscopic antenna array like approach. The simulation enables detailed visualization of the electromagnetic fields re-radiated by the RIS under various operating conditions. The RIS can be configured to operate either as an anomalous reflector or as a focusing lens. Both functionalities apply to transmissive and reflective RIS configurations.本数据集包含MATLAB程序"RIS_Simulator_CNIT.mat"及其关联函数，该程序基于类宏观天线阵列方法开发，用于模拟可重构智能表面（Reconfigurable Intelligent Surfaces，RIS）的工作特性。该仿真可实现对RIS在多种工作工况下再辐射电磁场的精细化可视化呈现。RIS可被配置为反常反射体或聚焦透镜两种工作模式，且上述两种功能均适用于透射式与反射式RIS构型。
