在牛肉模型中沿着垂直和水平轴的选定点，测量了由工作在13.56 MHz的原型三电极电容加热装置产生的初始温度升高。通过调整驱动装置上下两个电极的三个发电机提供的净功率，可以显著地操纵沿着牛肉幽灵垂直“中心”轴的初始温度高度分布。例如，在17厘米厚的模体中，通过适当地重新分配三个电极的功率，在上表面以下1和8厘米的中心轴深度处的初始温度升高比从3.2降低到0.5。
Measurements of initial temperature elevations produced by a prototype, three-electrode capacitive heating device operating at 13.56 MHz were made at selected points along vertical and horizontal axes in beef phantoms. Adjustment of the net power supplied by the three generators driving the upper and lower two electrodes of the device permitted significant manipulation of the distribution of initial temperature elevations along the vertical "central" axis of the beef phantoms. For example, in a 17 cm thick phantom, the ratio of initial temperature elevations at central axis depths of 1 and 8 cm below the upper surface was reduced from 3.2 to 0.5, through appropriate redistribution of power to the three electrodes.
