Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, Volume 38, Issue 32, 8 June 2026.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,
