Electromagnetic Analysis of Intelligent Reflecting Surface

Intelligent reflecting surfaces (IRSs) are a new type of reconfigurable metasurface that can be used to control the propagation of electromagnetic waves. This paper presents a MATLAB and Simulink code that can be used to perform the electromagnetic analysis of IRSs. The code is based on the finite element method and can be used to simulate the propagation of electromagnetic waves through a variety of IRS configurations. The code is also capable of generating the reflection coefficients for different incident configurations. The code is validated by comparing the results of the simulations with the results of analytical calculations. The results show that the code is able to accurately predict the performance of IRSs.
