Given this magnetic flux density as a limiting value, the maximum possible power reception is calculated according to equation (5) and using equation (6), which already takes resonant operation into account. The results are shown in Figure 9 for different receiver sizes. A frequency dependent
quality factor of the resonant circuit is assumed for the calculations, based on a frequency independent coil resistance. This resistance is selected to achieve a quality factor of 100 at 1 MHz. Thus, the assumption would further lead to a quality factor 1000 at 10 MHz.
