Selection of Incident Electric fields for Estimating the Calibration Factor of the Lead Electromagnetic Model

Using several sets of incident electric fields (Etan) with different profiles we estimated the calibration factors of the lead electromagnetic model for two helical coax leads at 128 MHz. The proposed quantities for E
_tan
selection are (i) the unitless ratio of the RF-induced power deposition (P) with the lead in place to P without the lead in place (P
_backgnd
) and (ii) the percentage of P
_backgnd
for the selected E
_tan
to that P
_backgnd
generated by a homogeneous E
_tan
.
