In one of our test coupons with $(n, k)=(25, 37)$, we even measured \emph{higher} inductance compared to a -simple two-layer planar spiral inductor. We suspect that this increase in inductance is due to the twists of our twisted -inductor effectively forming the structure of a planar toroidal inductor, with twisted inductors with $k\gg n$ -approximating planar toroidal inductors. In particular, except for the slight curvature of our twisted inductor's -traces, a twisted inductor with $(n, k)=(1, n')$ \emph{is} effectively a planar toroidal inductor with turn count $n'$. - -We suspect that for some choices of parameters, this effect might lead to an appreciable increase in useful inductance -as well as potentially interesting high-frequency behavior, and we aim at producing additional simulations and new -measurements for some of these choices of parameters in a future paper. +the extraction of FEM meshes from not just individual planar components, but PCBs in any file format supported by +gerbonara such as KiCad's native file format, as well as the Gerber file format supported by the majority of EDA tools. \section{Conclusion}
