Numerical simulation results of |B1+| over the entire head obtained with a sleeve of HDC material of BaTiO3 located inside the coil (first row), and outside the coil with four different thicknesses of 5, 10, 15, and 20 mm (second to fifth row). The uniformity of the |B1+| within the ROI (rectangular dashed line in second and third column) was improved up to 27% (outside 10 mm). Values were normalized to have average |B1+| = 4 µT at the ROI.
