S-parameter comparison between simulations and experiments of the Tic Tac Toe 16-channel Tx head coil. In (a), the FDTD simulated s-matrix using a transmission line model mechanism; in (b), the experimentally measured s-matrix of the constructed head coil. The color scale limits were modified to compensate for the electrical losses in the constructed coil (not included in FDTD model).
