\caption{The coupling between a pair of identical coils (here with $n=3$ and $k=4$) visualized in three dimensions.
The $x$ and $y$ axis show in-plane displacement, and the $z$ axis shows output amplitude in arbitrary units. Height
and rotation are fixed to \qty{1}{\milli\meter} and \qty{15}{\degree}, respectively. The most prominent aspects of
this plot are that coupling falls off steeply with distance, and that the rotation-dependent variation is small in
comparison. The circular valley around the central peak is the region where one inductor is mostly outside the other
inductors, and intersects the field lines returning from the other inductor's back, leading to a negative coupling
coefficient.}

\caption{The test schematic used in all measurements. For direct coupling factor measurements, the load resistor was
disconnected. We measure voltage at the output of the function generator to account for drop in its internal output
resistance.}
