“…However, for the investigated implants the RF fields arising from the model perturbation approach zero magnitude at the location of the RF coil. The final reason for a mismatch between the proposed method and the FDTD simulation is that there are inherent differences between the FDTD and VIE methods 34 , 35 . While the VIE method has been adapted to closely resemble the FDTD method, by having the same Yee cell discretization and dielectric averaging, the method for solving the RF fields is still different and could explain the found underestimation.…”

“…In this subsection, in order to demonstrate the superior convergence properties of the proposed high-order currentbased solver, in comparison with the flux-based formulation [29], [30], often used in MRI studies [16], [59], we conduct the computations for the EM scattering of a plane wave for the "Billie" RHBM from Virtual Family Population [47]. In detail, we operate at B 0 = 7 T, hence the corresponding frequency is f = 298.06 MHz and we irradiate the RHBM with an xpolarized and negative y-directed plane wave e inc = xe ik0y , so that the plane wavefront is parallel to the coronal plane of the RHBM.…”
