\caption{Inductor sample design parameters and measured characteristics for a number of physically larger,
ring-shaped inductors. $L$ and $R_\text{ESR}$ have been measured with a Keysight U1733C handheld LCR meter.
$f_\text{Res}$ has been measured with a LiteVNA VNA. $C_p$ has been calculated for the simple parallel LC resonator
model from $f_\text{Res}$ and $L$. $f_\text{Res}$ could not be measured for the $n=1$ case since these are just
planar toroidal inductors, which show different resonance characteristics compared to planar spiral or multi-turn
twisted inductors.}

\subsection{Coupling and its Sensitivity to Radial Offset}
The key performance criterion in our application is the voltage ripple that appears on the secondary side of a WPT link
