=3.52 (where the subscript MS denotes the addition of the metasurface), indicating drastic noise reduction. SNR results show that the bio-inspired coil alone provides a 28% improvement over a conventional circular coil, while adding the metasurface yields an additional 44% enhancement (84% overall). These results highlight the potential of combining bio-inspired geometries with flexible metasurfaces for high-sensitivity ultra-high-field MRI.
