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.
