Mutual Coupling Effects on Intelligent Reflecting Surfaces: Comparative Energy Efficiency and Transmit Power Analysis Versus Decode-and-Forward Relaying
— Intelligent Reflecting Surfaces (IRS) have emerged as a promising technology for enhancing wireless communication by smartly propagating signals with large, reconfigurable meta-surfaces. While recent foundational literature has benchmarked IRS performance under ideal, uncoupled physical models, practical deployments...
