The presented framework is physically grounded, enabling information-theoretic analyses that inherently incorporate correlation and mutual coupling among the antennas. This establishes the combined effects of correlation and coupling on the information-theoretic performance limits across SNR levels. Additionally, it reveals that, by suitably selecting the individual antenna patterns, mutual coupling can be harnessed to either reinforce or counter spatial correlations as appropriate for specific SNRs, thereby improving the performance. https://hdl.handle.net/10230/72914 Holographic MIMO Mutual coupling Fading correlation Channel capacity SNR-limiting analysis Mutual coupling in holographic MIMO: physical modeling and information-theoretic analysis
