TABLE IV.
Top ten simulated designs by heating zone aspect ratio, with relevant performance data. Diameter, length, and aspect ratio are measured from the SAR = 30 W∕kg isocontour. Several of these designs create reflection coefficients that would increase cable shaft heating and degrade performance in tissue.
