The things I do like about this article is the trends that the analysis predicts, which are generally correct. Trends such as:1) forward and return conductor proximity reduces group delay and increases bandwidth
2) small conductors exhibit less skin-effect and therefore can achieve higher bandwidth and less group delay change
3) low conductivity materials exhibit very large skin-depth and therefore do not suffer from skin-effect much, but they suffer from fixed attenuation at all frequencies
Some of the things that are not modeled are:
1) multistrand effects that increase inductance due to conductor surface oxides
2) an effective tradeoff between wire diameter and spacing, given skin-effects
3) contrasting requirements of interconnects versus spaeker cables
