Fig. 7: Numerical and experimental \({{\bf{B}}}_{{\bf{1}}}^{{\boldsymbol{+}}}\) magnitude and phase profiles.

Simulated (a) and measured (b) \({{\bf{B}}}_{{\bf{1}}}^{{\boldsymbol{+}}}\) vs. depth profiles for the LWA and fractionated dipole antenna element in the phantom (profiles were plotted along the corresponding dashed lines shown in Fig. 6a–d); simulated phase patterns for \({{\bf{B}}}_{{\bf{1}}}^{{\boldsymbol{+}}}\) in the phantom for the dipole antenna at 298 MHz (c), and for the LWA at 250 MHz (d), 298 MHz (e) and 350 MHz (f). The tangent to the phase front for each phase pattern is indicated with a black dashed line.
