Physics-Based Modeling and Scalable Optimization of Large Intelligent Reflecting Surfaces

Intelligent reflecting surfaces (IRSs) have the potential to transform wireless communication channels into smart reconfigurable propagation environments. To realize this new paradigm, the passive IRSs have to be large, especially for communication in far-field scenarios, so that they can compensate...
