We investigated the impact of coupling (magnitude and phase) on the B1+ field distribution and intensity of a 30-channel double-rowed Tic-Tac-Toe (TTT) RF array. We found that by changing the coupling of the TTT coil modules, we are able to modify the B1+ distribution from a single channel and how the B1+ field intensity is spread between different Z levels of the 30-channel array. This effect was seen in both simulations and experimental B1+ maps.
