Abstract
We explore the effects of various receiver coil dimensions and
configurations on power transfer efficiency and cost of operation, using
advanced simulation tools. We demonstrate that the spatial distribution
of the magnetic field leads to a non-monotonic dependence of the
coupling coefficient on coil size. Thus, an optimal coil size, where the
coupling coefficient peaks, should be regarded a crucial design
parameter which affects the entire system performances. The
incorporation of our findings into a multi-objective optimization
algorithm is also discussed.
