A novel approach for improving B1+ homogeneity in the abdominal area at 3T MRI is proposed and demonstrated numerically and experimentally. The approach is implemented via the ultralight and thin metasurface. The metasurface consists of metal wires loaded with capacitors printed on a flexible dielectric substrate of polyimide. Numerical studies and imaging of a volunteer covered with the proposed metasurface showed the same homogeneity of the transmit radiofrequency field distribution at the region-of-interest as the conventional dielectric pads.
