Electric near-field measurements confirm that the electric fields within the phantom are very well be affected by the dielectric pads. The data presented here indicate an agreement between simulations and measurements of electric and magnetic fields in the order of ~10%. This means that realistic scenarios can be evaluated with this error margin to provide SAR estimates for using pads in vivo.
