In this paper, we designed and fabricated a kind of metamaterial with 9×9 cells, which bent on phantom and inserted to a birdcage volume coil to investigate the performance for 3T MRI. The results of simulations and phantom experiments agreed with each other very well indicate that the proposed metamaterial is able to increase the B1+ fields in some region closed to the surface of phantom. This improvement of B1+ fields will benefit to 3T MRI targeted clinical applications.
