Full-wave frequency-domain electromagnetic modelling of RF fields in MRI applications

We show that full-wave frequency-domain electromagnetic (EM) methods can be efficiently used in RF designs for magnetic resonance imaging (MRI) applications. We also compare the results obtained by the higher order surface integral equation (SIE)-based method of moments (MoM) and the finite element method (FEM), namely, HFSS, which are in excellent agreement. Finally, we present important details of MoM-SIE and FEM (HFSS) modeling, which enable rigorous analyses and cross-validation of the solutions.
