The clearest modern statement of the near-field/far-field boundary for large arrays. Introduces the near-field focusing viewpoint and the additional rank it provides.

The original experimental observation of the keyhole phenomenon in MIMO. Historically important; establishes the rank-1 pathology that RIS rediscovers as a design feature.

Classical outdoor MIMO measurement and modeling paper. Discusses keyhole channels in street-canyon and hallway scenarios — the same geometry that RIS tries to enable deliberately.

CommIT contribution. The near-field coupling between a small active array and a large passive RIS produces a high-rank BS-RIS channel, enabling multi-user multiplexing. The practical rationale for the near-field analysis of Section 3.4.
