Global Optimal Closed-Form Solutions for Intelligent Surfaces With Mutual Coupling: Is Mutual Coupling Detrimental or Beneficial?

This repository contains code to reproduce the paper:

Code

The script main_gen_ZIIs.m generates the file ZIIs-d-lambda-n.mat, for n = 1, ..., 4, containing the mutual coupling matrices when the ratio between the wavelength and the inter-element distance is n. These .mat files are then used by the other scripts to plot all the figures.

The script main_Fign.m reproduces Fig. n, for n = 3, ..., 6.
