 \section{Experimental Validation}
 
+To experimentally validate our design with real-world inductors, we produced test coupons with a number of variations of
+twisted inductors with winding count $n$ between $1$ and $25$, and twist count ranging from $k=0$ (simple single-sided
+spiral inductor) to $k=37$.
