On the effects of mutual coupling in holographic MIMO

Holographic MIMO refers to a planar array with a massive number of antennas that are individually controlled and densely deployed in a space-constrained factor form at the base station. Understanding the fundamentals of Holographic MIMO communications requires to take into account the mutual coupling that have been typically overlooked in the vast majority of past and recent MIMO literature. This is particularly true in the Massive MIMO literature, which is all about using physically large arrays. The aim of this talk is to shed a light on the effects of mutual coupling in Holographic MIMO communications.
